Examples
- This thesis work has researched the fabrication technics of photonic crystal defect waveguide with air - bridge structure and collecting waveguide ; suggested using uv - lithography and wet etching to fabricate traditional waveguide , after that , using eb - lithography and dry etching to fabricate photonic crystal holes , so can reduce the fabrication cost by a big range ; designed the moulding board , which can fabricate the air - bridge structure and is convenient for recognizing position in eb - lithography ; the structure consisted of traditional waveguides and etching grooves are fabricated on soi successfully , then an successful eb - lithography is realized on the structure , the defect waveguide collected with the traditional waveguide quite well ; used the etching grooves to do the sacrificial layer etching experiment , which grounded etching sacrificial layer by photonic crystal holes in next step
提出采用紫外光刻工艺制作传统波导结构之后，通过电子束曝光和干法刻蚀制作光子晶体小孔的工艺方案，大幅度减低了制作成本；设计出可形成空气桥结构、并且适用于电子束曝光位置识别的光刻模板，在soi材料上成功制作出带有空气桥刻蚀预留槽以及接续光波导的结构，在该结构上成功实现了光子晶体带隙波导的电子束曝光，带隙波导与接续光波导位置接续良好；最后利用预留槽进行了刻蚀牺牲层的实验，为下一步利用光子晶体小孔刻蚀牺牲层形成空气桥结构打下了基础。
