In optoelectronics, semiconductors form the basis of most laser diodes, semiconductor optical amplifiers, modulators, and photodetectors. As an essential component of optical fiber communication, optical modules are optoelectronic devices that facilitate the conversion between optical and electrical signals during the transmission process. The choice of material for these chips—primarily Indium Phosphide (InP), Gallium Arsenide (GaAs), and Silicon (Si) —is a complex trade-off governed by a few key.
