Polarization Splitting Grating Coupler for Optical Antenna of LiDARs Consisting of Two Gratings Coupling Light in a Perfectly Vertical Direction

open access: yesIEEE Photonics Journal, 2021
Grating couplers (GCs) are devices for transmitting and receiving the light propagated in a waveguide in silicon photonic integrated circuits (PICs). In this study, we propose a polarization splitting GC (PSGC) for the optical antenna of light detection ...

Silicon-on-insulator nanophotonics [PDF]

open access: yesSPIE Proceedings, 2005
Nanophotonics promise a dramatic scale reduction compared to contemporary photonic components. This allows the integration of many functions onto a chip. Silicon-on-insulator (SOI) is an ideal material for nanophotonics. It consists of a thin layer of silicon on top of an oxide buffer.

Silicon-on-insulator photonic crystal miniature devices with slow light enhanced third-order nonlinearities [PDF]

open access: yes, 2012
The effects of the slow-down factor on third-order nonlinear effects in silicon-on-insulator photonic crystal channel waveguides were investigated. In the slow light regime, with a group index equal to 99, these nonlinear effects are enhanced but the ...
