Abstract
Combinations of optically coupled Generalized Mach-Zehnder Interferometers (GMZIs) result in switches of greater switching capacity than an isolated GMZI. In a preferred form, the present invention provides a balanced non-blocking switch by using symmetrical configurations of optically coupled GMZIs, and also provides a cascaded non-blocking switch by cascading an N×N GMZI with a (N−1)×(N−1) non-blocking switch.
