Abstract
A photonic integrated circuit (I/C) includes a focusing sidewall or in-plane surface that redirects and focuses light from a waveguide to a photodetector structure. The focusing includes redirecting an optical signal to a width smaller than a width of the waveguide. The focusing of the light allows the photodetector structure to be outside a waveguide defined by parallel oxide structures. With the photodetector structure outside the waveguide, the contacts can be placed closer together, which reduces contact resistance.
