本論文成功製作以及研究可全光調控之全方向性染料摻雜膽固醇液晶填入光子晶體光纖與共軸毛細管微雷射器。製作上，將雷射與偶氮染料摻雜膽固醇液晶材料選擇性地填充入光子晶體光纖之纖心與外殼或共軸毛細管之內管管心與內外管間細縫。在光子晶體光纖之纖心內或在共軸毛細管內管管心的雷射染料摻雜膽固醇液晶會自組裝為徑向對稱分布之平面結構，其可視為具光學活性之布拉格洋蔥狀共振腔。而在光子晶體光纖之外殼內或在共軸毛細管內外管間縫隙的偶氮染料摻雜膽固醇液晶會自組裝為焦錐狀結構，其可視為具可全光且可全方向控制之光學開關。
來自於雷射染料摻雜膽固醇液晶填充區的雷射可藉由偶氮染料摻雜膽固醇液晶填充區之全光控制造成全方向或部份方向輸出或完全不輸出。此全光控制機制乃藉由偶氮染料受紫外光與藍光分別照射後產生反-順與順-反異構化，進一步造成偶氮染料摻雜膽固醇液晶填充區在散射的焦錐態與穿透的各方同性態之間做等溫相變轉換。本論文所提出的全光調控光纖與毛細管雷射在生物影像、光療法、穿戴式裝置、透明顯示器等各方面皆極具應用潛力。

This thesis successfully develops and investigates all-optically and omni-directionally controllable dye-doped cholesteric liquid crystal (DDCLC) infiltrating photonic crystal fiber (PCF) and coaxial capillary (CC) lasers. In the process of fabrication, the laser dye-doped CLC (LDDCLC) and azo-dye-doped CLC (ADDCLC) selectively infiltrate into the core and cladding of the PCF sample, that is, the internal capillary and the gap between the internal and external capillaries of the CC sample, respectively. The LDDCLC in the core of the PCF or the internal capillary of the CC self-organizes as a radially symmetric planar structure, consequently enabling the LDDCLC to function as an optically active Bragg-onion cavity. By contrast, the ADDCLC in the cladding of the PCF or the gap of the CC self-organizes as a focal conic structure. As a result, the ADDCLC functions as an all-optically and omni-directionally controllable light shutter.
The lasing output from the LDDCLC-filled region can be all-optically controlled to emit omni-directionally or semi-directionally or off-emit in the isothermal phase transition between scattering focal conic state and transparent isotropic state through the UV beam-induced trans-cis and blue beam-induced cis-trans back isomerizations of the azo LCs in the ADDCLC-filled region. The potential of all-optically controllable PCF or CC in bio-image, photo-therapy, wearable devices, and transparent displays is significant.
