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Grating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。

光敏電阻結合光纖之傳感器在結構與土木工程的應用

為了解決Grating的問題，作者龔慕萱 這樣論述：

近年來，隨著各種結構物的增加，土木研究方向逐漸由新建結構物轉變為對舊有結構物的加固與監測，也因此結構健康監測(Structural Health Monitoring, SHM)開始受到重視，各種不同的傳感器也開始受到研究。其中光纖作為傳感器擁有體積小、傳輸速度快、監控範圍大、傳輸距離遠、抗腐蝕與抵抗電磁干擾等優勢，並且在測量應變、應力、溫度與各種結構物之物理變化皆有高敏感度與準確性，所以被廣泛應用於各種結構檢測之中。也因光纖傳感器擁有強大的測量效果，能搭配光纖傳感器的測量工具也大量被研究。本研究選用光敏電阻結合光纖作為一低成本的光纖傳感器，直接測量通過光纖之光強度變化，並使用樹莓派(Ras

pberry Pi)作為此光敏電阻傳感器之接收端。實驗方面從水質濁度監測試驗、光纖彎曲監測試驗以及震動試驗來判斷光敏電阻作為傳感器的精確度與可行性，同時進行結果分析判斷未來改善之方向。試驗結果顯示，此光敏電阻傳感器在光纖彎曲時或是進入光纖之光強度改變時可以有效並準確測量出光訊號的差異，然而在光強度高頻率改變的測量環境下，可能因為光敏電阻的時延性導致精確度下降，因此此傳感器可能較不適合使用於高頻率環境之測量。
