PD in optical module
A photodiode is a semiconductor device that converts light into electrical current. As a core component of optical transceiver modules, these devices ensure seamless high-speed data transmission across networks. These packages have multiple pins and leads that are connected via wiring to the internal semiconductor chip and other parts. Thin-film filter and PLC based AWG for multiplexing, a full suite of components for optical amplification use, optomechanical or MEMS-based switches for protection or surveillance application, Tap PD for power monitoring and VOA for. The Monitor Photodiode (MPD) chip, is a planar light-receiving structure and has a large photosensitive surface of 200μm. It is used in the TO-CAN package of the TO56 laser with the long wavelength range of 980nm-1620nm in optical communication to monitor the back light of the laser chip.
