Abstract

The backreflection in commonly used grating couplers on silicon-on-insulator (SOI) is not negligible for many
applications. This reflection is dramatically reduced in our improved compact grating coupler design, which directs the reflection away from the input waveguide. Realized devices on SOI show that the reflection can be reduced
down to −50 dB without an apparent transmission penalty.
