We have designed a grating coupler on Silicon-on-Insulator (SOI) platform that has sufficient bandwidth to cover the entire CWDM O-band from 1270 nm to 1330 nm. The grating architecture is inspired by adjoint method-based geometry optimization, and then parameterized to accommodate DOE construction for tapeouts at commercial CMOS foundries and wafer-level testing on fiber probe stations. One grating design achieved peak loss of 3.2 dB with 1-dB bandwidth spanning from 1265 nm to 1338 nm in simulations.Recently, spati
