Vivek Singh,Pao Tai Lin,Neil Patel,Hongtao Lin,Lan Li,Yi Zou,Fei Deng,Chaoying Ni,Juejun Hu,James Giammarco,Anna Paola Soliani,Bogdan Zdyrko,Igor Luzinov,Spencer Novak,Jackie Novak,Peter Wachtel,Sylvain Danto,J. David Musgraves,Kathleen Richardson,Lionel C. Kimerling,Anuradha M. Agarwal +20 more
TL;DR: This article discusses the design of mid-IR chalcogenide waveguides integrated with polycrystalline PbTe detectors on a monolithic silicon platform for optical sensing, wherein the use of a low-index spacer layer enables the evanescent coupling ofMid-IR light from the waveguide to the detector.
