High speed, and high optical bandwidth, resonant cavity enhanced sensitivity light detector of high efficiency

摘要

A single photodetector having a light detector with high efficiency in the wide optical band takes Hiromitsu band, said photodetector: the first diode region of the first doping type for receiving light; are second thickness and; active regions of third thickness which is present between the second diode region and said first diode region, converted into an electronic signal light received in the: second diode region of the second doping type by binding to the second diode region includes a reflector having a silicon layer having a thickness of 4 which is present between the silicon oxide layer having a thickness of 5, the active region is light of a wavelength of 900nm is less than absorb, the reflector reflects the light in the wavelength range of 1380nm to 1260nm, a single receiver.
