Diffraction gratings based on multilayer silicon nitride waveguide with high upward efficiency and large effective length
Wen-ling Li, Jing-wei Liu, Guo-an Cheng +3
Diffraction gratings with high upward diffraction efficiency and large effective length are required for chip-scale light detection and ranging. In this paper, we propose a diffrac…

Linear absorption coefficient of in-plane graphene on a silicon microring resonator
Heng Cai, Yahui Cheng, He Zhang +4
We demonstrate that linear absorption coefficient (LAC) of a graphene-silicon hybrid waveguide (GSHW) is determined by the optical transmission spectra of a graphene coated symmetr…
