High-speed III-V nanowire photodetector monolithically integrated on Si
Abstract
Direct epitaxial growth of III-V on Si for optical emitters and detectors remains a challenge. Here, the authors demonstrate in-plane monolithic integration of an InGaAs nanostructure p-i-n photodetector on Si capable of high-speed optical data reception at 32 Gbps enabled by a 3 dB bandwidth exceeding 25 GHz.
