Due to the popularity of the Internet and video-on-demand services, the capacity of photon network systems must be increasing. The semiconductor photodetector converts the optical signal into an electrical signal is a key device for the receiver in the photon network system. General requirements for photodetectors are: in order to achieve a higher bit rate, it takes a faster-operating speed; in...
The photodetector realizes the role of converting light into electricity in the optical communication system. This is mainly based on the photovoltaic effect of semiconductor materials. The so-called photovoltaic effect refers to the uneven semiconductor or semiconductor and metal bonding between different parts of the light. The phenomenon of potential difference. With the continuous...
