ABSTRACT:
An optical noise source. An optical amplifier produces unpolarized optical noise by spontaneous emission. The optical noise is emitted from one side of the amplifier and filtered by a bandpass filter to attenuate any noise having a wavelength outside a desired bandspread. The filtered noise is reflected back through the amplifier for one additional amplification and then emitted from the other side of the amplifier through a nonreflecting output.
