| Summary: | 碩士 === 國立交通大學 === 電子工程系所 === 92 === In this research, we investigate the ARROW-based coherently coupled bending waveguides. The transfer matrix method and effective index method are used to analyze the rib-ARROW structures. The beam propagation method is used to simulate the propagation performance of the ARROW-based bending waveguides. Due to the adjustable characteristics of waveguide width and rib depth, we propose flexible bending devices based on rib-ARROW’s structures. When the total bending angles are designed as 27.2°, 36.8° and 91.2°, respectively, the corresponding waveguide widths are 5.0 mm, 4.0 mm and 4.0 mm, respectively. Furthermore, the corresponding device transmissions and device areas are 0.828 (0.82 dB), 0.746 (1.27 dB), 0.610 (2.15 dB) and 1.32 mm2, 1.24 mm2, 9.54 mm2, respectively.
