9.5 Semiconductor avalanche photodiode (APD) In order to improve detection sensitivity, the pin photodetector discussed in the previous section often needs to be followed by a discrete or pin-integrated field effect transistor (FET) to amplify the weak electrical signal received. The avalanche effect is just the working principle of apd, and is not the same thing as the working mode. The apd working mode is divided into Geiger mode and linear mode. The difference is that the linear mode bias voltage is lower than the reverse breakdown voltage, and the Geiger mode bias voltage is higher than the breakdown voltage. Linear.
