[[alternative]]Study of 32x32 Arrayed Waveguide Grating Based on SOI

[[abstract]]In this thesis, we design a 32×32 Arrayed Waveguide Grating (AWG) wavelength switch which combines arrayed waveguide grating and electrooptic phase modulator based on silicon-on-insulator (SOI) wafer. In arrayed waveguide grating, we use the technique of the constant path length difference at adjacent waveguide of waveguide array to realize the spatial and spectrum division, and discuss the waveguide separation influence at the junction of free propagation region and arrayed waveguide. We also concern the insertion loss and crosstalk affected by tapered waveguide at the interface between the input/output waveguide and free propagation region. We derive the phase term effect at the waveguide array of the arrayed waveguide grating, and with different modulation method to let arrayed waveguide grating get a new function. In 32×32 AWG wavelength switch, we focus on the new technology of router. The 32×32 AWG wavelength switch which combines AWG structure and electrooptic phase modulation structure. The boron and phosphorus ions are assumed doping on aside of waveguide array and add voltage to change the carrier concentration distribution. By changing carrier concentration distribution, the index can be changed. We can switch the specific wavelength form the output port of waveguide. We apply such a device into a optical network using finite wavelength channel numbers.
