Heterostructure crystals could light the way to optical circuits

It may be possible to reach new levels of miniaturization, speed, and data processing with optical quantum computers, which use light to carry information. For this, we need materials that can absorb and transmit photons. Scientists have introduced a new strategy for constructing photonic heterostructure crystals with tunable properties. Using a crystalline rod with stripes that fluoresce in different colors, they have developed a prototype of a logic gate.
