Abstract:
A simple method for improving the input coupling in uncleaved waveguide photodetectors is demonstrated. A wedge-shaped recess is incorporated into the input facet to reduce reflection. Over a range of device sizes and wedge shapes, mean quantum efficiency was increased by 16% relative to flat, uncleaved input facets.
