For now, photonic chips can't be conventional chips.

Optical chip simply refers to the photonic chip. The application of optical chips to processors such as mobile phones, notebooks, and desktops, completely replacing the mainstream silicon-based chips in the market, has always been the direction of development in the field of science and technology. So far, the research and application of optical chips are still in a small range, and have not replaced silicon chips. With the advancement of science and technology, that day will come.
It is impossible for photonic chips to replace electronic ones. Because both the input of the data and the output of the result are required to convert the electronic signal into an optical signal or the optical signal into an electronic signal. Although it is not possible to replace electronic chips at this stage, photonic chips have higher computing speeds, lower power consumption and latency, and are not susceptible to changes in temperature, electromagnetic fields and noise.
