Demonstration of a low loss, highly stable and re-useable edge coupler for high heralding efficiency and low g^(2) (0) SOI correlated photon pair sources
Jinyi Du, George F. R. Chen, Hongwei Gao +3
We report a stable, low loss method for coupling light from silicon-on-insulator (SOI) photonic chips into optical fibers. The technique is realized using an on-chip tapered wavegu…

Optical characterization of deuterated silicon-rich nitride waveguides
Xavier X. Chia, George F. R. Chen, Yanmei Cao +3
Chemical vapor deposition-based growth techniques allow flexible design of CMOS-compatible materials. Here, we report the deuterated silicon-rich nitride films grown using plasma-e…
