Abstract

The compatibility of silicon photonics and silicon electronics allows for the development monolithic devices to meet the scale and performance required for quantum technologies such as quantum information processing. We present a monolithic electronic-photonic homodyne detector with a bandwidth of 19.8 GHZ. This outperforms any previous demonstrations and is directly attributable to the monolithic integration that limits the parasitic capacitance typical from packaging and interfacing multiple integrated circuits.
