Abstract
An optical light source signal generator comprising an optical amplification medium for generating amplified spontaneous emission (ASE), having forward and backward light propagating ports for outputting output and backward optical light respectively, a reflector for reflecting the backward propagating optical light back toward the backward light propagating port, and an optical light spectrum reshaper interposed between the reflector and the backward light propagating port for transmitting the reflected light to the backward light propagating port with a wavelength dependence having a reduced amplitude in a band coinciding with an undesired high gain band of the optical amplification medium.
