Abstract :
We demonstrated an optical gain equalization and manipulation approach using all-optical liquid-crystal devices and the harmonic synthesis approach. The optical harmonic equalizers (OHEs) dynamically adjust the gain profiles by generating the required transfer functions with a series of variable harmonic filters.
