Control of optical properties through photochromism: a promising approach to photonics

Abstract

Abstract In this work studies on photochromism for optics and photonics are reviewed. The versatility of organic chemistry gives photochromic materials wide opportunities for several applications that range from tunable filters and gratings, to refractive‐index modulators for optical fibers and communications, to optical memories and sensors. Moreover, novel results on amplified emission efficient modulation in a conjugated polymer/photochromic system are presented.
