PROCESS FOR FABRICATION OF HIGH REFLECTORS BY REVERSAL OF LAYER SEQUENCE AND APPLICATION THEREOF

摘要

An optical reflector includes an optical reflective element that comprises alternating layers of high and low index layers. A new substrate is bonded on the optical reflective element. The sequence of layers in the reflective element is reversed in order such that the layers grown first with lowest surface roughness are exposed to the highest electric field strength, and the layer grown last, of highest roughness, are buried deep in the multilayer stack.
