Abstract:
A high contrast grating optoelectronic apparatus includes an optoelectronic device at a front surface of a substrate. The optoelectronic device is to one or both of emit light and detect light through a back surface of the substrate opposite the front surface. A high contrast grating (HCG) lens is adjacent to and spaced apart from the back surface of the substrate by a spacer. The spacer includes one or both of a wafer-bonded substrate and a cavity. The HCG lens is to focus the light.
