We show that SNSPDs can also be used to study continuous variables of optical quantum states by performing homodyne detection at a bandwidth of 400 kHz. By measuring the interference of a continuous-wave field of a local oscillator with the field of the vacuum state using two SNSPDs, we show that the variance of the difference in count rates is linearly proportional to the photon flux of the local oscillator over almost five orders of magnitude. The resulting shot-noise clearance of (46.0 ± 1.1) dB is the highest reported clearance for a balanced optical homodyne detector, demonstrating their potential for measuring highly squeezed states in the continuous-wave regime. In addition, we measured a CMRR = 22.4 dB. From the joint click counting statistics, we also measure the phase-dependent quadrature of a weak coherent state to demonstrate our device’s functionality as a homodyne detector.","lang":"eng"}]},{"year":"2024","citation":{"bibtex":"@article{Thiele_Hummel_Lange_Dreher_Protte_Bruch_Lengeling_Herrmann_Eigner_Silberhorn_et al._2024, title={Pyroelectric influence on lithium niobate during the thermal transition for cryogenic integrated photonics}, volume={4}, DOI={10.1088/2633-4356/ad207d}, number={1015402}, journal={Materials for Quantum Technology}, publisher={IOP Publishing}, author={Thiele, Frederik and Hummel, Thomas and Lange, Nina Amelie and Dreher, Felix and Protte, Maximilian and Bruch, Felix vom and Lengeling, Sebastian and Herrmann, Harald and Eigner, Christof and Silberhorn, Christine and et al.}, year={2024} }","mla":"Thiele, Frederik, et al. “Pyroelectric Influence on Lithium Niobate during the Thermal Transition for Cryogenic Integrated Photonics.” Materials for Quantum Technology, vol. 4, no. 1, 015402, IOP Publishing, 2024, doi:10.1088/2633-4356/ad207d.","chicago":"Thiele, Frederik, Thomas Hummel, Nina Amelie Lange, Felix Dreher, Maximilian Protte, Felix vom Bruch, Sebastian Lengeling, et al. “Pyroelectric Influence on Lithium Niobate during the Thermal Transition for Cryogenic Integrated Photonics.” Materials for Quantum Technology 4, no. 1 (2024). https://doi.org/10.1088/2633-4356/ad207d.","apa":"Thiele, F., Hummel, T., Lange, N.

However, integrating single-photon detectors requires cryogenic operating temperatures, since the best performing detectors are based on narrow superconducting wires. While previous studies have demonstrated the operation of quantum light sources and electro-optic modulators in LiNbO3 at cryogenic temperatures, the thermal transition between room temperature and cryogenic conditions introduces additional effects that can significantly influence device performance. In this paper, we investigate the generation of pyroelectric charges and their impact on the optical properties of lithium niobate waveguides when changing from room temperature to 25 K, and vice versa. We measure the generated pyroelectric charge flow and correlate this with fast changes in the birefringence acquired through the Sénarmont-method. Both electrical and optical influence of the pyroelectric effect occur predominantly at temperatures above 100 K.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1088/2633-4356/ad207d","date_updated":"2024-03-04T13:20:43Z","publication_status":"published","publication_identifier":{"issn":["2633-4356"]},"title":"Pyroelectric influence on lithium niobate during the thermal transition for cryogenic integrated photonics"},{"user_id":"48188","date_created":"2024-03-26T08:52:05Z","status":"public","volume":6,"publication":"Physical Review Research","keyword":["General Physics and Astronomy"],"publisher":"American Physical Society (APS)","author":[{"full_name":"Arends, Christian","first_name":"Christian","id":"43994","last_name":"Arends"},{"last_name":"Wolf","id":"45027","first_name":"Lasse Lennart","full_name":"Wolf, Lasse Lennart"},{"full_name":"Meinecke, Jasmin","first_name":"Jasmin","last_name":"Meinecke"},{"id":"48188","last_name":"Barkhofen","full_name":"Barkhofen, Sonja","first_name":"Sonja"},{"id":"49178","last_name":"Weich","full_name":"Weich, Tobias","orcid":"0000-0002-9648-6919","first_name":"Tobias"},{"id":"49683","last_name":"Bartley","full_name":"Bartley, Tim","first_name":"Tim"}],"issue":"1","article_number":"L012043","intvolume":" 6","_id":"52876","type":"journal_article","citation":{"ieee":"C.

Combining these characteristics with temporal control of SNSPDs broadens their applications as in active de-latching for higher dynamic range counting or temporal filtering for pump-probe spectroscopy or LiDAR. To that end, we demonstrate active gating of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length of 5.0 ns. We show how the rise time depends on the inductance of the detector in combination with the control electronics. The gate window is demonstrated to be fully and freely, electrically tunable up to 500 ns at a repetition rate of 1.0 MHz, as well as ungated, free-running operation. Control electronics to generate the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat, while the detector is operated on the cold stage at 0.8 K. We show that the efficiency and timing jitter of the detector is not altered during the on-time of the gating window. We exploit gated operation to demonstrate a method to increase in the photon counting dynamic range by a factor 11.2, as well as temporal filtering of a strong pump in an emulated pump-probe experiment."}],"user_id":"83846"},{"language":[{"iso":"eng"}],"doi":"10.1021/acs.nanolett.2c04980","oa":"1","date_updated":"2023-05-12T11:17:51Z","publication_status":"published","publication_identifier":{"issn":["1530-6984","1530-6992"]},"project":[{"name":"TRR 142: TRR 142","_id":"53"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - B09: TRR 142 - Subproject B09","_id":"170"},{"_id":"171","name":"TRR 142 - C07: TRR 142 - Subproject C07"},{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"}],"department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"title":"Compact Metasurface-Based Optical Pulse-Shaping Device","type":"journal_article","year":"2023","citation":{"ieee":"R.

The working principle meanwhile gives rise to the crucial problem and challenge to protect the metasurface from dust or clean the unavoidable contaminants during daily usage. Here, taking advantage of the intelligent bioinspired surfaces which exhibit self-cleaning properties, a versatile dielectric metasurface benefiting from the obtained superhydrophilic or quasi-superhydrophobic states is shown. The design is realized by embedding the metasurface inside a large area of wettability supporting structures, which is highly efficient in fabrication, and achieves both optical and wettability functionality at the same time. The superhydrophilic state enables an enhanced optical response with water, while the quasi-superhydrophobic state imparts the fragile antennas an ability to self-clean dust contamination. Furthermore, the metasurface can be easily switched and repeated between these two wettability or functional states by appropriate treatments in a repeatable way, without degrading the optical performance. The proposed design strategy will bring new opportunities to smart metasurfaces with improved optical performance, versatility, and physical stability."}],"volume":10,"status":"public","has_accepted_license":"1","date_created":"2021-10-25T06:34:38Z","quality_controlled":"1","author":[{"full_name":"Lu, Jinlong","first_name":"Jinlong","last_name":"Lu"},{"first_name":"Basudeb","full_name":"Sain, Basudeb","last_name":"Sain"},{"last_name":"Georgi","full_name":"Georgi, Philip","first_name":"Philip"},{"full_name":"Protte, Maximilian","first_name":"Maximilian","last_name":"Protte"},{"last_name":"Bartley","id":"49683","first_name":"Tim","full_name":"Bartley, Tim"},{"first_name":"Thomas","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas","last_name":"Zentgraf","id":"30525"}],"publisher":"Wiley","publication":"Advanced Optical Materials","file_date_updated":"2021-10-25T06:42:52Z","file":[{"date_created":"2021-10-25T06:42:52Z","file_name":"AdvOptMat_Lu_2021.pdf","access_level":"closed","file_size":2801333,"creator":"zentgraf","file_id":"26748","date_updated":"2021-10-25T06:42:52Z","content_type":"application/pdf","success":1,"relation":"main_file"}],"article_number":"2101781","issue":"1","intvolume":" 10","_id":"26747","citation":{"ama":"Lu J, Sain B, Georgi P, Protte M, Bartley T, Zentgraf T.

The operation voltage \r\n \r\n \r\n \r\n V\r\n \r\n π\r\n \r\n /\r\n \r\n 2\r\n \r\n \r\n \r\n \r\n of these modulators increases, due to the decrease in the electro-optic effect, by 74% for the phase modulator, 84% for the directional coupler and 35% for the polarisation converter below 8.5\r\n \r\n \r\n \r\n K\r\n \r\n \r\n \r\n . The phase modulator preserves its broadband nature and modulates light in the characterised wavelength range. The unbiased bar state of the directional coupler changed by a wavelength shift of 85\r\n \r\n \r\n \r\n n\r\n m\r\n \r\n \r\n \r\n while cooling the device down to 5\r\n \r\n \r\n \r\n K\r\n \r\n \r\n \r\n . The polarisation converter uses periodic poling to phasematch the two orthogonal polarisations. The phasematched wavelength of the utilised poling changes by 112\r\n \r\n \r\n \r\n n\r\n m\r\n \r\n \r\n \r\n when cooling to 5\r\n \r\n \r\n \r\n K\r\n \r\n \r\n \r\n .","lang":"eng"}],"user_id":"83846","publication":"Journal of Physics: Photonics","keyword":["Electrical and Electronic Engineering","Atomic and Molecular Physics","and Optics","Electronic","Optical and Magnetic Materials"],"author":[{"last_name":"Thiele","id":"50819","first_name":"Frederik","full_name":"Thiele, Frederik","orcid":"0000-0003-0663-5587"},{"id":"71245","last_name":"vom Bruch","full_name":"vom Bruch, Felix","first_name":"Felix"},{"full_name":"Brockmeier, Julian","first_name":"Julian","id":"44807","last_name":"Brockmeier"},{"id":"46170","last_name":"Protte","full_name":"Protte, Maximilian","first_name":"Maximilian"},{"full_name":"Hummel, Thomas","first_name":"Thomas","id":"83846","last_name":"Hummel"},{"first_name":"Raimund","full_name":"Ricken, Raimund","last_name":"Ricken"},{"last_name":"Quiring","full_name":"Quiring, Viktor","first_name":"Viktor"},{"first_name":"Sebastian","full_name":"Lengeling, Sebastian","last_name":"Lengeling","id":"44373"},{"full_name":"Herrmann, Harald","first_name":"Harald","id":"216","last_name":"Herrmann"},{"full_name":"Eigner, Christof","orcid":"https://orcid.org/0000-0002-5693-3083","first_name":"Christof","id":"13244","last_name":"Eigner"},{"id":"26263","last_name":"Silberhorn","full_name":"Silberhorn, Christine","first_name":"Christine"},{"last_name":"Bartley","id":"49683","first_name":"Tim","full_name":"Bartley, Tim"}],"publisher":"IOP Publishing","date_created":"2022-10-11T07:14:40Z","status":"public","volume":4,"intvolume":" 4","_id":"33672","issue":"3","article_number":"034004","citation":{"mla":"Thiele, Frederik, et al. “Cryogenic Electro-Optic Modulation in Titanium in-Diffused Lithium Niobate Waveguides.” Journal of Physics: Photonics, vol. 4, no. 3, 034004, IOP Publishing, 2022, doi:10.1088/2515-7647/ac6c63.","bibtex":"@article{Thiele_vom Bruch_Brockmeier_Protte_Hummel_Ricken_Quiring_Lengeling_Herrmann_Eigner_et al._2022, title={Cryogenic electro-optic modulation in titanium in-diffused lithium niobate waveguides}, volume={4}, DOI={10.1088/2515-7647/ac6c63}, number={3034004}, journal={Journal of Physics: Photonics}, publisher={IOP Publishing}, author={Thiele, Frederik and vom Bruch, Felix and Brockmeier, Julian and Protte, Maximilian and Hummel, Thomas and Ricken, Raimund and Quiring, Viktor and Lengeling, Sebastian and Herrmann, Harald and Eigner, Christof and et al.}, year={2022} }","chicago":"Thiele, Frederik, Felix vom Bruch, Julian Brockmeier, Maximilian Protte, Thomas Hummel, Raimund Ricken, Viktor Quiring, et al. “Cryogenic Electro-Optic Modulation in Titanium in-Diffused Lithium Niobate Waveguides.” Journal of Physics: Photonics 4, no. 3 (2022). https://doi.org/10.1088/2515-7647/ac6c63.","ama":"Thiele F, vom Bruch F, Brockmeier J, et al.

We present a method to replace the electrical input by supplying the required bias current via the photocurrent of a photodiode situated on the cold stage of the cryostat. Light is guided to the bias photodiode through an optical fiber, which enables a lower thermal conduction and galvanic isolation between room temperature and the cold stage. We show that an off-the-shelf InGaAs–InP photodiode exhibits a responsivity of at least 0.55 A/W at 0.8 K. Using this device to bias an SNSPD, we characterize the count rate dependent on the optical power incident on the photodiode. This configuration of the SNSPD and photodiode shows an expected plateau in the single photon count rate with an optical bias power on the photodiode above 6.8 µW. Furthermore, we compare the same detector under both optical and electrical bias, and show there is no significant changes in performance. This has the advantage of avoiding an electrical input cable, which reduces the latent heat load by a factor of 100 and, in principle, allows for low loss RF current supply at the cold stage.
