A photodiode is a type of photodetector that functions similar to a regular signal diode, but generates a photoelectric current when absorbing light in the depletion region of the junction semiconductor. Photodiodes have two operating modes: photoconductive mode (reverse bias) or photovoltaic mode (zero bias), and the choice of operating mode depends on the speed requirements in the application and the allowable magnitude of dark current (leakage current). It is necessary to accurately determine the desired output current level and responsiveness based on the incident light. Our company provides a series of fiber optic coupled, high-speed, and high bandwidth detectors. The TVS-PD series photodetectors operate in reverse bias mode and have a bias battery inside. They are output through SMA coaxial connectors and can be directly connected to an oscilloscope for monitoring, making it convenient to detect the pulse sequence of ultrafast exciters.
