查询词典 whispering voice

Owing to the geometrical symmetry of microdisk cavities, they support whispering gallery modes in which light circulates around the periphery of the structure and is confined by total internal reflections at both the sidewall and the top and bottom surfaces of the MD.

在微碟共振腔圆柱对称的结构中，电磁场藉由在碟缘墙面上全反射环绕而形成共振，产生所谓的WGM模态，透过湿式蚀刻，让微碟上下表面暴露於空气中，使相对折射率差异大，因而场型更能够对称地被局限在微碟共振腔内。

When the fiber is bent,the light ejects from the fundamental mode to form whispering gallery modes produced by reflection at the cladding-coating interface,or at the coating-air interface. On the synchronous coupling condition,the light from the WG modes will couple back and interfere with the fundamental mode,which leads to bending loss oscillations.

光纤弯曲时，从基模辐射出去的一部分能量在包层涂敷层或涂敷层空气界面处发生反射形成回音壁模，当满足同向耦合条件时，WG模又重新耦合回纤芯与基模发生干涉，使光纤的弯曲损耗产生振荡。

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。
