Design of 2x2 Optoelectronic Switch Based on MZI and Study the Effect of Electrode Switching Voltages

a 2x2 optoelectronic switch based on Mach-Zehnder interferometer. The designed model has a very high switching capability and is extremely reliable and has been devised keeping in view some inherent drawbacks like cost of higher driving voltage, high losses, polarization dependent losses and crosstalks. The various design parameters have been varied to improve the performance of the switch. A comprehensive study has been made on the effect of switching voltages on the switching properties with reference to the optical field propagation and refractive index propagation. However switch sizes larger than 2 x 2 can be realized by appropriately cascading small switches. The main considerations in building large switches are number of small switches required, loss uniformity, number of cross overs and blocking characteristics.
