BROAD-BAND OPTICAL REFLECTOR - AN APPLICATION OF LIGHT LOCALIZATION IN ONE-DIMENSION

A broad-band optical reflector based on the localization of light for one-dimensional disordered systems is proposed and demonstrated both t heoretically and experimentally The binary disordered multilayer refle ctor consists of alternating random layers of two coating materials. I ts high reflection range is much wider than that of standard lambda/4 stacks and can be obtained by a conventional coating method and ordina ry materials. This kind of reflector will have significant application s in laser technology and optical equipment. (C) 1995 American Institu te of Physics.
