吴奕德91M01：利用真空湿式反应室进行即时就地胶原蛋白固定之研究。

In this dissertation, InGaAs/InGaAsP/InP MQW microdisk laser and its characterization were presented. Some conclusions are as following: the characteristics of lasing threshold was discussed by using rate equation. The dependent relations between threshold and cavity volume, spontaneous emission coupling efficiency β were investigated. The whispering gallery mode and spontaneous emission in a microdisk geometry were then studied. Almost all spontaneous emission was coupled into the lowest order TE mode when the normalized thickness of photonics well was between 0.15 and 0.5. The design principle and device process of InGaAs/InGaAsP/InP MQW microdisk laser were presented. The microdisk lasers with the diameter of 8μm, 4. 5μm and 2μm were succesfully fabricated by using etching techniques. The pulse lasing thresholds for the microdisk with the diameter of 8μm and 4. 5μm were 170μW and 15μW, a record results compared with the published in the literature. The cw lasing threshold for a 2-μm-diameter microdisk was only a few μW. We haven't found similar report up to now. To solve the problem of directional output in a microdisk laser, the power coupling efficiency in a double disk geometry was investigated with the theory of waveguide mode couple. A new structure of electrically pumped microdisk laser with output waveguide was designed, making a foundation for the practical use of microdisk laser.

本文主要研究InGaAs/InGaAsP/InP多量子阱半导体碟型激光器的研制和特性表征，并取得如下结果：利用速率方程理论讨论了激光器激射阈值的特性，分析了阈值与腔体积和自发发射耦合系数β之间的关系；讨论了微碟光子阱结构中的自发发射特性和微碟中WGM模式特性；光子阱结构在其归一化厚度在0.15-0.5之间时，几乎全部自发发射进入到最低阶TE模式中；研究了InGaAs/InGaAsP/InP多量子阱微碟激光器的结构设计原理和器件的制备工艺；利用刻蚀方法成功制备出直径分别为8μm、4.5μm、2μm的碟型微腔激光器；直径8μm和4.5μm的微碟脉冲光泵浦激射阈值分别为170μW、15μW，是目前所见文献报导中比较低的；直径2μm的微碟连续光泵浦激射阈值仅几μW，目前尚未见到达到类似结果的研究报导；为解决微碟激光器激射光定向引出的问题，通过波导耦合模理论分析了双层碟之间功率耦合效率；据此设计了新型带耦合输出波导的电泵浦微腔激光器，为进一步研制可实用的电泵浦微腔激光器打下基础。

This issue in order to focus on "post-colonial criticism"(Yi Xiao-bin ,2004:64-68) for perspective, from a historical and cultural background to be, as well as the characterization of discourse analysis,"Robinson Crusoe" set up by the The sovereign state / colony, his master / slave, white / color, cultural center / edge of culture, civilization / barbarity, Christian / tribal people, such as food dualistic system of colonial discourse deconstruction, revealing the implication of colonialism in the works Awareness and to explain how the guns Robinson backed in a planned way from the language of religious belief and two of the "Friday" naked colonial culture, it lost its original cultural identity, resulting in self-identity Loss of the dilemma.

本课题着重以"后殖民主义批评"（易小斌，2004：64-68）为视角，拟从历史文化背景、人物刻画以及话语分析入手，对《鲁滨逊漂流记》中所建立起的宗主国/殖民地，奴隶主/奴隶，白种人/有色人，中心文化/边缘文化，文明/野蛮，基督教/食人部族等二元对立的殖民话语体系进行解构，揭示蕴涵在作品中的殖民主义意识，并阐释鲁滨逊如何以枪炮为后盾，有计划地从语言和宗教信仰两方面对"星期五"进行赤裸裸的文化殖民，使其丧失了原有的民族文化身份，从而造成自我身份丧失的窘境。
