The difference between photonic chips and electronic chips

The difference between photonic chips and traditional electronic chips lies in the different computing media.

High-end electronic chips require the use of high-precision EUV lithography machines to carve chip circuits on silicon wafers and integrate tens of billions of transistors.

Photonic chips use light waves as the carrier of information transmission and data calculation, so they do not require high-precision lithography machines. my country's current level of lithography machines can also meet basic needs.

Materials such as gallium arsenide (shen) and indium phosphide (yin) used in photonic chips can allow photonic chips to have higher-speed data transmission and data processing capabilities and lower costs. The power consumption can effectively solve the problem of poor battery life of current electronic devices.

The current development of China's photonic chips:

Because our country is in urgent need of getting rid of its dependence on Western countries in the field of chips, in addition to continuing to dig deeper in the field of traditional electronic chips, it is also developing photonic chips. To achieve overtaking on this new road, Beijing and Shanghai have introduced relevant incentive policies around photonic chips. Now many companies have begun to enter the field of photonic chips.
