Glasses as Nonlinear Photonic Materials

The success of photonic switching depends on the development of the materials and devices that are capable of processing light signals without converting them to electronic forms. Glasses are promising materials for these all‐optical devices because of their fast‐responding nonlinearities and low absorption. The aim of this paper is to apprise the ceramic community of the development of nonlinear optics research. The relative merits and trade‐offs of glasses as nonlinear photonic material are discussed.
