A wafer structure includes a diffractive lens disposed on a backside of a wafer and coupled to a front side waveguide, the diffractive lens being configured to receive light and focus the light to the front side waveguide.

Backside binary grated lens coupled to front side waveguide

A method of manufacturing a device includes forming an optical coupler having a first end contacting a front side of a semiconductor substrate and a second end contacting an optical waveguide on an insulator layer on the substrate. The optical coupler is curved between the first end and the second end. The optical coupler is configured to change a direction of travel of light from a first direction at the first end to a second direction at the second end.
