第二曲率半徑-
Second, the mode fields of a strip waveguide and some slab waveguides have been simulated by applying finite - difference time - domain ( fdtd ) method. the curvature radius ; vicinity coupling ; transition loss and power attenuation of a s - shape bend waveguide have been analysed numerically by employing wide angle finite - difference beam propagation method ( fd - bpm ), as well as the coupling loss of optical fiber and waveguide. in addition, the framework of the s - shape waveguide laser has been
其次,應用時域有限差分法,結合波導模式理論對條形與平面波導進行了模場模擬;應用廣角有限差分光束傳播法,對s形彎曲波導的曲率半徑、鄰近耦合、過渡損耗、功率衰減以及波導與光纖的各種耦合損耗進行了數值分析,並在此基礎上,對s形波導激光器的結構作了初步設計。 -
