[{"abstract":[{"text":"We review our results of numerical simulations of light scattering from different systems of densely packed irregular particles. We consider spherical clusters, thick layers and monolayers with realistic topologies and dimensions much larger than the wavelength of light. The maximum bulk packing density of clusters is 0.5. A numerically exact solution of the electromagnetic problem is obtained using the Discontinuous Galerkin Time Domain method and with application of high- performance computing. We show that high packing density causes light localization in such structures which makes an impact on the opposition phenomena: backscattering intensity surge and negative linear polarization feature. Diffuse multiple scattering is significantly reduced in the case of non-absorbing particles and near-field interaction results in a percolation-like light transport determined by the topology of the medium. With this the negative polarization feature caused by single scattering gets enhanced if compared to lower density samples. We also confirm coherent double scattering mechanism of negative polarization for light scattered from dense absorbing slabs. In this case convergent result for the scattering angle polarization dependency at backscattering can be obtained for a layer of just a few tens of particles if they are larger than the wavelength.","lang":"eng"}],"publication":"Springer Series in Light Scattering - Volume 8: Light Polarization and Multiple Scattering in Turbid Media","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"keyword":["tet_topic_scattering"],"type":"book_chapter","date_created":"2022-09-22T09:18:45Z","file":[{"file_id":"33467","content_type":"application/pdf","file_name":"2022-09 Grynko - Book chapter on Light Scattering by Large Densely Packed Clusters of Particles.pdf","access_level":"local","file_size":1525307,"relation":"main_file","date_updated":"2022-09-22T09:24:45Z","date_created":"2022-09-22T09:24:45Z","creator":"fossie"}],"intvolume":" 8","date_updated":"2023-01-11T15:28:17Z","publication_status":"published","publication_identifier":{"issn":["2509-2790","2509-2804"],"isbn":["9783031102974","9783031102981"]},"author":[{"full_name":"Grynko, Yevgen","last_name":"Grynko","first_name":"Yevgen","id":"26059"},{"full_name":"Shkuratov, Yuriy","last_name":"Shkuratov","first_name":"Yuriy"},{"full_name":"Alhaddad, Samer","first_name":"Samer","last_name":"Alhaddad","id":"42456"},{"full_name":"Förstner, Jens","first_name":"Jens","last_name":"Förstner","orcid":"0000-0001-7059-9862","id":"158"}],"title":"Light Scattering by Large Densely Packed Clusters of Particles","year":"2022","doi":"10.1007/978-3-031-10298-1_4","series_title":"Springer Series in Light Scattering","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://rdcu.be/cV5GC"}],"project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"ama":"Grynko Y, Shkuratov Y, Alhaddad S, Förstner J.

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.

These applications require state-of-the-art engineering to reach optimized functionalities such as high directivity and radiation efficiency, low sidelobe levels, broadband and tunable capabilities, and compact design. In this work, we report on the numerical optimization of the directivity of optical traveling wave antennas made from low-loss dielectric materials using full-wave numerical simulations in conjunction with the particle swarm optimization algorithm. The antennas are composed of a reflector and a director deposited on a glass substrate, and an emitter placed in the feed gap between them serves as an internal source of excitation. In particular, we analyze antennas with rectangular- and horn-shaped directors made of either hafnium dioxide or silicon. The optimized antennas produce highly directional emissions due to the presence of two dominant guided TE modes in the director in addition to leaky modes. These guided modes dominate the far-field emission pattern and govern the direction of the main lobe emission, which predominately originates from the end facet of the director. Our work also provides a comprehensive analysis of the modes, radiation patterns, parametric influences, and bandwidths of the antennas, which highlights their robust nature."}],"issue":"1","publication":"Journal of the Optical Society of America B","keyword":["tet_topic_opticalantenna"],"type":"journal_article","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"file":[{"content_type":"application/pdf","file_id":"28417","date_updated":"2021-12-08T08:26:57Z","relation":"main_file","embargo":"2022-12-08","file_size":14029741,"creator":"fossie","access_level":"local","file_name":"2021-12 Farheen - JOSA B - Optimization of optical nanoantennas.pdf","date_created":"2021-12-08T08:26:57Z","embargo_to":"open_access"},{"creator":"fossie","date_created":"2021-12-08T08:29:49Z","file_size":655495,"access_level":"open_access","file_name":"2021-12 Farheen - JOSA B - Optimization of optical nanoantennas SUPPLEMENTARY MATERIAL.pdf","date_updated":"2021-12-08T08:29:49Z","relation":"supplementary_material","content_type":"application/pdf","file_id":"28418"}],"date_created":"2021-12-08T07:14:39Z","has_accepted_license":"1","status":"public","ddc":["530"],"user_id":"158","volume":39,"page":"83","_id":"28413","project":[{"name":"TRR 142","_id":"53","grant_number":"231447078"},{"name":"TRR 142 - Project Area C","_id":"56"},{"grant_number":"231447078","_id":"75","name":"TRR 142 - Subproject C5"},{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"file_date_updated":"2021-12-08T08:29:49Z","citation":{"chicago":"Farheen, Henna, Till Leuteritz, Stefan Linden, Viktor Myroshnychenko, and Jens Förstner. “Optimization of Optical Waveguide Antennas for Directive Emission of Light.” Journal of the Optical Society of America B 39, no. 1 (2022): 83. https://doi.org/10.1364/josab.438514.","short":"H.

Our antennas contain a director and reflector deposited on a glass substrate, which are excited by a dipole emitter placed in the feed gap between the two elements. Full-wave simulations in conjunction with global optimization provide structures with an enhanced linear directivity as high as 119 radiating in the substrate. The high directivity is a result of the interplay between two dominant TE modes and the leaky modes present in the antenna director. Furthermore, these low-loss dielectric antennas exhibit a near-unity radiation efficiency at the operational wavelength of 780 nm and maintain a broad bandwidth. Our numerical results are in good agreement with experimental measurements from the optimized antennas fabricated using a two-step electron-beam lithography, revealing the highly directive nature of our structures.

Here, we report a method to increase a metasurface’s versatility by covering the high-index metasurface with a low index porous SiO2 film, protecting the metasurface from environmental changes while keeping the working efficiency unchanged.

Cavities with low Q-factors are generally given less attention due to their high losses that quickly destroy quantum systems. However, bad cavities can be utilized for several applications, where lower Q-factors are required, e.g., to increase the spectral width of the cavity mode. In this work, we demonstrate that low-Q cavities can be beneficial for preparing specific electronic steady states when certain quantum states of light are applied. We investigate the interaction between quantum light with various statistics and matter represented by a Λ-type three-level system in lossy cavities, assuming that cavity losses are the dominant loss mechanism. We show that cavity losses lead to non-trivial electronic steady states that can be controlled by the loss rate and the initial statistics of the quantum fields. We discuss the mechanism of the formation of such steady states on the basis of the equations of motion and present both analytical expressions and numerical simulations for such steady states.","lang":"eng"}],"date_created":"2023-01-18T10:56:13Z","type":"journal_article","keyword":["General Physics and Astronomy"],"department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"623"},{"_id":"35"}],"status":"public","publisher":"IOP Publishing","_id":"37318","user_id":"16199","volume":24,"citation":{"bibtex":"@article{Rose_Tikhonova_Meier_Sharapova_2022, title={Steady states of Λ-type three-level systems excited by quantum light with various photon statistics in lossy cavities}, volume={24}, DOI={10.1088/1367-2630/ac74d8}, number={6063020}, journal={New Journal of Physics}, publisher={IOP Publishing}, author={Rose, Hendrik and Tikhonova, O V and Meier, Torsten and Sharapova, Polina}, year={2022} }","ama":"Rose H, Tikhonova OV, Meier T, Sharapova P.

Several different approaches to realize solid-state quantum emitters with high performance have been pursued and different concepts for energy tuning have been established. However, the properties of the emitted photons are always defined by the individual quantum emitter and can therefore not be controlled with full flexibility. Here we introduce an all-optical nonlinear method to tailor and control the single photon emission. We demonstrate a laser-controlled down-conversion process from an excited state of a semiconductor quantum three-level system. Based on this concept, we realize energy tuning and polarization control of the single photon emission with a control-laser field. Our results mark an important step towards tailored single photon emission from a photonic quantum system based on quantum optical principles."}],"publication":"Nature Communications","issue":"1","department":[{"_id":"15"},{"_id":"297"},{"_id":"230"},{"_id":"429"},{"_id":"27"},{"_id":"623"},{"_id":"170"},{"_id":"35"}],"type":"journal_article","keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"date_created":"2023-01-27T13:41:42Z"}]
