Abstract

The switching characteristic of wide-band MSM and PIN photodetectors has been studied in theory and experiments. MSM detector has threshold bias voltage to activate its response and so has a better performance than PIN photodetectors when working as a photo-electronic switch. However, our study tells that through a suitable designed bias circuit, the PIN photodetector also can provide a switching operation with considerable performance. Especially for RF photonic signal, the extinction ratio can reach around 30dB. At different bias condition, the gain of PIN can be continually tuned and it has very important application in photonic phased-array antenna system.
