In the realm of fiber optic communication, photodetectors, or photodiodes play a pivotal role in converting optical signals into electrical data. As a core component of optical transceiver modules, these devices ensure seamless high-speed data transmission across networks. A photodiode is a semiconductor diode sensitive to photon radiation, such as visible light, infrared or ultraviolet radiation, X-rays and gamma rays. It produces an electrical current when it absorbs photons.
