A photodetector in optical communication is a crucial component that converts light signals into electrical signals. Typically made from materials like silicon or indium gallium arsenide, it detects the modulated light transmitted through optical fibres. The photodetector’s sensitivity and speed determine the effectiveness of signal reception and overall system performance. It plays a vital role in ensuring accurate data transmission by translating optical pulses into electronic signals that c...
