A spontaneous emission source bias a high spectral density at a desired wavelength. An integrated guided wave optical path is formed in either a semiconductor or silica substrate. An active medium and grating are provided within the optical path. The optical path is pumped to pass energy across the grating and active medium. The pump energy excites the active medium without lasing to output spontaneous emissions at a wavelength established by the grating. The source is particularly useful for reducing nonlinear effects in an optical fiber used for communicating AM or other information signals.
