| 摘 要： | 针对目前纳米光波导传输中散射损耗严重的问题,详细分析了表面粗糙度与波导宽度对散射损耗的影响,给出了清晰的对应关系图。设计并采用MEMS工艺制备出纳米光波导结构,在此基础上对波导结构进行了表面粗糙度的测试,进一步提出采用高温热处理方法使波导表面粗糙度降低了3 nm左右。实验发现:高温热处理后的光波导结构其散射损耗降低到3.343 dB/cm。

| Abstract: | Aiming at current serious problem that scattering loss in nano-optical waveguide transmission,effect of surface roughness and waveguide width on scattering loss is analyzed in detail,and clear figure of corresponding relation is given.MEMS technique is designed and used to manufacture nano-optical waveguide structures.On the basis of this test of surface roughness of optical waveguide structure is taken.Moreover,waveguide surface roughness is reduced about 3nm by the hyperthermia heat treatment method.The experimental data shows that scattering loss is reduced to 3.343 dB/cm after hyperthermia. |
