On-Chip Microresonators: A Game-Changer for Quantum Information Processing and Optical Communications

Microresonators are tiny devices that are capable of confining light to a very small volume, typically on the order of micrometers or less. They are usually made of materials with high refractive indices, such as silicon or silica, and are used in a variety of applications, including optical communication, sensing, and signal processing. The basic…
