ABSTRACT:
An optical RF bandpass filter employing a noncoherent optical carrier. The filter consists of a section of multimode optical fiber having a length equal to half the modulation wavelength with mirrors deposited at each end of the fiber. The fiber section functions as a resonant cavity for the intensity modulated light which is directed into the fiber and which exits at one end through one of the partially reflecting mirrors.
