Abstract In this thesis, we introduce a new optical device, which is the integrated optical polarizer. It is based on the Silicon Hollow Waveguide. This choice is made to make the device fabrication compatible with MEMS process. We use the Photonic Crystals structures to achieve the required polarizer high extinction ratio. 2 types of polarizers are being introduced and analyzed. The first one is a 1D photonic crystal or multilayer polarizer. The advantage of this device is the relative simplicity of fabrication, as the multilayers are made of alternating layers of Air and Silicon. The extinction ratio (XR) in this case is reasonable. In order to increase this ratio, we will use the 2D photonic crystals, which achieves the desired very high XR. But this is done on the expense of the increased complexity of the device, and became more subject to process tolerance and variation. To model the effects of process randomness on the performance, a statistical analysis tool is developed based on Monte Carlo Simulation. For demonstration, the tool is applied on a typical device of the optical networks, which is the 2x2 switch, and we managed to optimize the design to enhance the yield, through analyzing the tool data. |
