Abstract
A zone plate, etched into the backend of a silicon-on-insulator chip, was designed to improve the optical coupling efficiency between grating couplers and non-perpendicular light sources with an elliptical beam profile. Measurements of a highly divergent light source showed efficiency improvements up to 8.7dB.
