Semiconductor-based optical switch architecture

摘要

A semiconductor-based optical switch engine switches input light from an input switch element to an output switch element and directly couples through an optical waveguide each output of the input switch element to a respective input of the output switch element. The switch architecture reduces signal cross-talk because each signal passes through the optical switch engine using a dedicated optical path. The optical switch engine also maintains a consistent signal-to-noise ratio among all the paths through the switch and reduces the total number of switch points through which an optical signal may pass.
