Abstract
A system for switching optical energy from a plurality of input waveguides to a plurality of output waveguides, while balancing power in the output waveguides, and a method for its use. The system is based on an optical switch matrix that includes, for each input waveguide and for each output waveguide, one or more attenuators that divert an adjustable portion of the optical energy, that enters via that input waveguide, to that output waveguide. Preferably, each input waveguide is coupled to each output waveguide via a pair of 2×2 Mach-Zehnder interferometers, a first of which has an idle input port and a second of which has an idle output port. The system also includes a feedback mechanism that taps fixed portions of the power in either the input waveguides or the output waveguides, and adjusts the attenuators accordingly.
