A continuous-wave laser beam is delivered and the squeezed field is collected by single-mode fibers; up to −3.17(9) dB of useful squeezing is available in fibers. To showcase the usefulness of such a fiber-coupled device, we applied the generated squeezed light in a fiber-based phase sensing experiment, showing a quantum enhancement in the signal-to-noise ratio of 0.35 dB. Moreover, our investigation of the effect of photorefraction on the cavity resonance condition suggests that it causes system instabilities at high powers.","lang":"eng"}],"user_id":"216","quality_controlled":"1","author":[{"last_name":"Domeneguetti","first_name":"Renato","full_name":"Domeneguetti, Renato"},{"first_name":"Michael","full_name":"Stefszky, Michael","last_name":"Stefszky","id":"42777"},{"first_name":"Harald","full_name":"Herrmann, Harald","last_name":"Herrmann","id":"216"},{"last_name":"Silberhorn","id":"26263","first_name":"Christine","full_name":"Silberhorn, Christine"},{"full_name":"Andersen, Ulrik L.","first_name":"Ulrik L.","last_name":"Andersen"},{"last_name":"Neergaard-Nielsen","first_name":"Jonas S.","full_name":"Neergaard-Nielsen, Jonas S."},{"first_name":"Tobias","full_name":"Gehring, Tobias","last_name":"Gehring"}],"publisher":"Optica Publishing Group","keyword":["Atomic and Molecular Physics","and Optics"],"publication":"Optics Letters","volume":48,"status":"public","date_created":"2023-07-25T10:35:24Z","intvolume":" 48","_id":"46138","article_number":"2999","issue":"11","type":"journal_article","citation":{"bibtex":"@article{Domeneguetti_Stefszky_Herrmann_Silberhorn_Andersen_Neergaard-Nielsen_Gehring_2023, title={Fully guided and phase locked Ti:PPLN waveguide squeezing for applications in quantum sensing}, volume={48}, DOI={10.1364/ol.486654}, number={112999}, journal={Optics Letters}, publisher={Optica Publishing Group}, author={Domeneguetti, Renato and Stefszky, Michael and Herrmann, Harald and Silberhorn, Christine and Andersen, Ulrik L. and Neergaard-Nielsen, Jonas S. and Gehring, Tobias}, year={2023} }","mla":"Domeneguetti, Renato, et al. “Fully Guided and Phase Locked Ti:PPLN Waveguide Squeezing for Applications in Quantum Sensing.” Optics Letters, vol. 48, no. 11, 2999, Optica Publishing Group, 2023, doi:10.1364/ol.486654.","ama":"Domeneguetti R, Stefszky M, Herrmann H, et al.

Our simulations show that double scattering between two random irregular particles shows weak NP. Adding one more particle significantly increases the relative contribution of double scattering which enhances NP. Simulations with regular shapes and controlled geometric parameters show that the interference mechanism is sensitive to the geometry of the scattering system and can also result in no polarization or even strong enhancement of positive polarization at backscattering."}]},{"issue":"2","intvolume":" 48","_id":"35128","year":"2022","type":"journal_article","citation":{"chicago":"Nikbakht, Hamed, Mohammad Talebi Khoshmehr, Bob van Someren, Dieter Teichrib, Manfred Hammer, Jens Förstner, and B.

The overall device size is 800 µm including in/out S-bend waveguides. The coupler is an asymmetric non-uniform directional coupler that consists of two tapered waveguides. One of the coupler arms is shifted by 100 µm in the propagation direction, which results in a more wavelength-insensitive 3-dB response compared to a standard (not shifted) coupler. Moreover, compared to a long adiabatic coupler, we achieved a similar wavelength response at a 16-times-smaller device length. The couplers were fabricated using the silicon nitride platform of Lionix International. We also experimentally demonstrated an optical switch that is made by using two of these couplers in a Mach–Zehnder interferometer configuration. According to experimental results, this optical switch exhibits –10 dB of extinction ratio over the 1500–1600 nm wavelength range. Our results indicate that this new type of coupler holds great promise for various applications, including optical imaging, telecommunications, and reconfigurable photonic processors where compact, fabrication-tolerant, and wavelength-insensitive couplers are essential."}],"status":"public","has_accepted_license":"1","date_created":"2023-01-03T09:32:47Z","volume":48,"file":[{"file_size":3731864,"embargo_to":"open_access","access_level":"local","file_name":"2023-01 Nikbakht - Optics Letter - Asymmetric, non-uniform 3-dB directional coupler with 300-nm bandwidth and small footprint.pdf","date_created":"2023-01-03T09:36:34Z","date_updated":"2023-01-03T09:36:34Z","content_type":"application/pdf","relation":"main_file","file_id":"35129","embargo":"2024-01-03","creator":"fossie"}],"author":[{"first_name":"Hamed","full_name":"Nikbakht, Hamed","last_name":"Nikbakht"},{"first_name":"Mohammad Talebi","full_name":"Khoshmehr, Mohammad Talebi","last_name":"Khoshmehr"},{"first_name":"Bob","full_name":"van Someren, Bob","last_name":"van Someren"},{"first_name":"Dieter","full_name":"Teichrib, Dieter","last_name":"Teichrib"},{"id":"48077","last_name":"Hammer","full_name":"Hammer, Manfred","orcid":"0000-0002-6331-9348","first_name":"Manfred"},{"id":"158","last_name":"Förstner","full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","first_name":"Jens"},{"last_name":"Akca","first_name":"B.

Transfer of\r\noptical power carried by planar, semi-guided waves is possible without reflections or radiation losses, and over large\r\nvertical distances. This functionality is realized through simple step-like folds of high-contrast dielectric slab waveguides, in combination with oblique wave incidence, and fulfilling a resonance condition. Radiation losses vanish, and polarization conversion is suppressed for TE wave incidence beyond certain critical angles. This can be understood by fundamental arguments resting on a version of Snell’s law. The two 90° corners of a step act as identical partial reflectors in a Fabry–Perot-like resonator setup. By selecting the step height, i.e., the distance between the reflectors, one realizes resonant states with full transmission. Rigorous quasi-analytical simulations\r\nfor typical silicon/silica parameters demonstrate the functioning. Combinations of several step junctions can lead\r\nto other types of optical on-chip connects, e.g., U-turn- or bridge-like configurations."}],"language":[{"iso":"eng"}],"doi":"10.1364/ol.40.003711","oa":"1","date_updated":"2022-01-06T06:59:51Z","publication_status":"published","publication_identifier":{"issn":["0146-9592","1539-4794"]},"department":[{"_id":"61"}],"title":"How planar optical waves can be made to climb dielectric steps"},{"abstract":[{"text":"We study the formation of subwavelength solitons in binary metal-dielectric lattices. We show that the transverse modulation of the lattice constant breaks the fundamental plasmonic band and suppresses the discrete diffraction of surface plasmon waves. New types of plasmonic solitons are found, and their characteristics are analyzed. We also demonstrate the existence of photonic-plasmonic vector solitons and elucidate their propagation properties.","lang":"eng"}],"article_type":"original","ddc":["530"],"user_id":"158","publication":"Optics Letters","file_date_updated":"2018-09-04T19:53:37Z","keyword":["tet_topic_polariton"],"author":[{"first_name":"Yao","full_name":"Kou, Yao","last_name":"Kou"},{"last_name":"Förstner","id":"158","first_name":"Jens","full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862"}],"publisher":"The Optical Society","file":[{"relation":"main_file","date_updated":"2018-09-04T19:53:37Z","content_type":"application/pdf","creator":"hclaudia","file_id":"3897","file_size":585088,"access_level":"open_access","file_name":"2015-03 Kou,Förstner_Subwavelength binary plasmonic solitons_Optics letters.pdf","date_created":"2018-08-13T10:23:50Z"}],"volume":40,"date_created":"2018-08-13T10:22:12Z","status":"public","has_accepted_license":"1","urn":"38960","_id":"3896","intvolume":" 40","issue":"6","page":"851-854","citation":{"short":"Y.
