Abstract
A device representing a reflector, for example, an evanescent reflector or a multilayer interference reflector with at least one reflectivity stopband is disclosed. A medium with means of generating optical gain is introduced into the layer or several layers of the reflector. The optical gain spectrum preferably overlaps with the spectral range of the reflectivity stopband. This device can be attached to air, semiconductor or dielectric material or multilayer structures and provide a tool for preferential amplification of the optical waves propagating at larger angles with respect to the interface with the evanescent or the multilayer interference reflector. Thus angle selective amplification or generation of light is possible. Several evanescent or interference reflectors can be used to serve the goal of preferable amplification the said optical waves.
