Grating coupler with reduced back reflection using λ/4 offset at its grating sub-teeth
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We demonstrate a grating coupler with reduced back reflection on silicon-on-insulator (SOI) platform. Each grating tooth of the grating coupler is uniformly divided into multiple sub-teeth with λ/4...
