Abstract
An optical system for controlling gain modification, including a first non-linear optical element (NLE) through which an input optical signal and a first pump wavelength are transmitted to generate a first optical signal; a second NLE through which the first optical signal is amplified to generate a second optical signal; a third NLE through which the second optical signal is amplified to generate a third optical signal; a first heating element coupled to the second NLE to adjust a temperature of the second NLE to control a first gain profile of the second optical signal; a second heating element coupled to the third NLE to adjust a temperature of the third NLE to control a second gain profile of the third optical signal, wherein the temperatures of the second and the third NLE minimize a gain modulation of the optical system based on the first and the second gain profiles.
