Abstract :
Power equalization in WDM systems can be achieved by a variety of means including signal pre-emphasis, fixed fiber gratings, and individual attenuators placed between two wavelength routers. Each of these approaches represents a tradeoff in network operator flexibility. In this paper, we demonstrate a dynamic WDM equalizer using a voltage-controlled variable reflectivity strip mirror and free-space wavelength multiplexing to provide dynamic control over wavelength power levels across a continuous transmission spectrum.
