Paper Abstract

The transmission properties of an interference filter with optical gain are studied in which the layers of a gain medium are stacked in a self-similar manner. It is found that the gain variation of transmitted light with layer thickness or input frequency exhibits a fractal structure with sharp gain peaks which are not observed for a multilayer with periodic gain structures.
