The most common materials include silicon, indium phosphide, gallium arsenide, and lithium niobate, each chosen for specific optical properties such as wavelength compatibility, power handling, and integration requirements. Photonic chips use specialised materials that enable light to travel through circuits instead of electrons. This technology detects, generates, transports, and processes light. They are responsible for generating laser light. Optical chip, generally refers to the use of light waves (electromagnetic waves) as the carrier of information transmission or data calculation, relying on integrated optics or silicon-based optoelectronics medium optical waveguide to transmit guided-mode optical signals, the modulation of optical. At the heart of every optical transceiver are semiconductor chips: the laser that emits the light and the photodetector that receives it.
