高功率可變出光角光子晶體面射型雷射之特性研究

為了解決Ecosystem的問題，作者陳立人 這樣論述：

本論文旨在研究高功率可變出光角之光子晶體面射型雷射的設計，製作及其光電特性。光子晶體面射型雷射因具備大功率操作及發散角小等特性，近年來頗受矚目，被視為是3D感測，光達，和雷射加工等應用領域的理想光源；研究首先藉由數值模擬計算來探討磊晶結構及光子晶體結構對於雷射閾值及出光效率的影響，進而得到較佳的磊晶結構同時配合不同的光子晶體結構來進行實驗驗證，實驗與模擬的結果均顯示雷射的斜率效率隨著光子晶體結構的對稱性下降而大幅上升，實驗並針對P面向上的結構進行優化，使得光輸出功率進一步提升，同時我們也針對大功率單模操作進行探討。另一方面我們也針對改變鐳射出光角度的機制進行研究以實現光束掃描的新奇雷射結構。

先後評估了主動式的光學相位陣列，主動式光柵結構，雙調變式光子晶體結構以及超穎結構等方式，考量結構整合的便利性及發光效率等因素，我們採用雷射整合表面超穎結構的方式進行設計，超穎結構的設計使用了奈米結構陣列及反向設計兩種方式，在砷化鎵基板上實驗的結果顯示此結構可將雷射光偏轉至設計的角度並且抑制原本垂直方向上的雷射光，此超穎結構結合光子晶體面射型雷射將得到高效率且緊湊的光束偏轉雷射，進一步製作成不同出光角度的陣列並單獨控制即可實現掃描功能，預期此雷射結構在上述的應用領域有著相當大的潛力。

Handbook of Air Quality and Climate Change

為了解決Ecosystem的問題，作者 這樣論述：

This handbook covers the air quality/air pollution from the viewpoints of causing impacts on human/ecosystem health and climate change. Traditionally, air pollution has been a concern mainly in terms of its impacts on human health, and it is still an immediate public and governmental concern in most

Asian countries. However, in recent years so-called extreme weather events, such as stronger tropical cyclones, flooding, drought, and other phenomena, have been manifested causing tremendous losses of human lives and properties. Importantly, climate models tell us that such extreme weather events

are actually induced by anthropogenic global warming. It has been pointed out that mitigation or alleviation of such climate change leading to the extreme weather events in the next 30 years can be possible only by reducing air pollutants with positive radiative forcing such as ozone or methane, whi

ch are called short-lived climate pollutants (SLCPs). Here, concerns about mitigation of air pollutants from the points of human health and climate change have merged. This book covers different kinds of air pollutants and radiative forcers and how they can be measured. It also mentions the situatio

n of air pollutants in different continents and their regional impacts to human health, environment and economy as well as their link to extreme weather events. The book presents how the air pollution and climate change can be mitigated and how clean air technologies and international initiatives fo

r co-controlling air pollution and climate change have been developed. Dr. Hajime Akimoto received his B.S. in 1962 and Ph.D. in 1967 in physical chemistry from the Tokyo Institute of Technology. For his postdoctoral research he spent 3 years, 1969-1971, in the Department of Chemistry at the Unive

rsity of California, Riverside, and worked on the chemistry of photochemical air pollution. In 1974 he joined the National Institute for Environmental Studies in Tsukuba, Japan, as the head of the Atmospheric Chemistry Section in the Atmospheric Environment Division, and then served as the chief of

the Atmospheric Environment Division and Global Environment Division.Subsequently, Dr. Akimoto moved to the Research Center for Advanced Science and Technology at The University of Tokyo as a professor in 1993. In 2000, he joined the Frontier Research Center for Global Change, now under the Japan Ag

ency for Marine-Earth Science and Technology as the director of the Atmospheric Composition Research Program. After 2010 he served as director general of the Asia Center for Air Pollution Research in Niigata, Japan. Currently, he is a guest scientist at the National Institute for Environmental Studi
