Abstract
A photodetector including a high electron mobility transistor (HEMT) device or an indium phosphide (InP)-based heterojunction bipolar transistor (HBT) device including a collector layer, a base layer formed on the collector layer and an emitter layer formed on the base layer. The photodetector also includes a nanowire array electrically coupled to the HEMT device or the base layer of the HBT device, and may include a first sub-array positioned on one side of the emitter layer and second sub-array positioned on an opposite side of the emitter layer. The nanowire array includes a plurality of spaced apart and conical-shaped InP nanowires encased in a transparent medium, and are operable to absorb light over a wavelength band of 400-925 nm and convert the light to an electrical signal that is received by the HEMT or HBT device.
