Simulation of an All-Optical 1 × 2 SMZ Switch With a High Contrast Ratio

Optical fibre communication system has become the backbone behind the Internet due to the huge capacity it offers. As the demand for network capacity is growing rapidly, there is a growing need for all optical based system that offer a much greater bandwidth compared to the traditional copper cables and other communications technologies. However, in conventional optical fibre communication networks the switching process is still performed in the electrical domain requiring Optical/Electrical/Optical (O/E/O) conversion. O/E/O conversion not only necessitate extra power, but it also entails speed bottleneck due to the data processing speed of the conventional electronic components currently limited to 40 Gbit/s.
