Credit: Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CASPhotonic integrated circuits (PICs) use photons as information carriers and feature ultra-high transmission speed, low delay, and anti-electromagnetic crosstalk. These advantages are expected to solve the bottleneck problems of microelectronic chips in terms of speed, power consumption, and integration density. It is of key…
