Design of 4x4 Banyan Optical Switch Using Optoelectronic MZI Switches with Low Crosstalk

We introduce here a designing of 2x2 MZI (Mach-Zehnder Interferometer) optical switch. The switching of the optical signal is realized with the use of fast electro-optical effects. The designed model has a very high switching capability and is extremely reliable. Various design parameters have been varied to improve the performance of the switch. Then the basic 2×2 switch is exploited in design of 4×4 banyan switch. Banyan switch is a good candidate for further use in higher order switches. Simulation results are shown for 2×2 and 4×4 banyan architecture with low cross-talk values.
