碩士 === 明新科技大學 === 電子工程研究所 === 97 === In this paper, using modified holographic optical switches to build the double-layer network (DLN) and dilated double-layer network (DDLN) have been proposed. The number of the required component and drivers are reduced and the insertion loss is significantly minimized. Additionally, one software program has been designed to simulate the 4×4 double-layer network, 8×8 double-layer network, 4×4 dilated double-layer network and 8×8 dilated double-layer network, which help to calculate the signal-to-noise ratio. Finally, the system signal-to-noise ratio keeps the original value by cascaded a polarizer at output ports.
