Optical chips are mainly used in the communication industry and are an indispensable part of the communication equipment system. The chip we often talk about is a silicon chip, which belongs to the semiconductor industry, such as CPU, storage, flash memory and so on. Optical chip is used to complete the conversion of photoelectric signals, is the core device, divided into active optical chip and passive optical chip.
Silicon is a semiconductor, silicon single crystal is the basic material of the chip, mainly using the semiconductor properties of silicon.
What is optical chip? The researchers combined the luminescent properties of indium phosphide with the optical routing capabilities of siliconSingle hybrid chip. When a voltage is applied to indium phosphide, light enters the silicon wafer's waveguide, producing a sustained laser beam that drives other silicon photonic devices.
