Not Accessible

Your library or personal account may give you access

Abstract

A novel photodetector, which uses a Si-based multi-cavity filter and an InP-based UTC photodetector, is demonstrated. The device has quantum efficiency of 55%, the excellent spectral response, and 3-dB bandwidth of 24 GHz.
