中文摘要：本研究計畫目標是針對半導體環型共振腔的空間光孤子激發機制的探討及其應用在光信號調制與傳輸控制的可行性研究，我們將延續100年度專題計畫半導體環形共振腔空間光孤子的激發研究成果為基礎，本計畫中將以雙Y-型藕合輸出之半導體環型共振腔雷射結構來激發產生空間光孤子，主要研究重點是探討環型共振腔電流注入對Y-型藕合輸出反方向光孤子激發的條件，同時進行Y-型偶合波導與空間光孤子波導間的光信號控制的研究，結果證實環型共振腔的輸出與Y-型波導光耦合會受到光孤子波導段的產生有顯著的改變，環型共振腔反時鐘方向的光大部分會耦合到光孤子波導端輸出，光孤子波導能夠達到光路徑的控制，本計畫所完成的結果可以對國內光孤子相關的應用研究提供基礎性的實驗數據參考。
英文摘要：Self-focusing of light due to optically induced index gradient arising in Kerr media1 has been attracted decades of investigation for generating spatial soliton. A spatial soliton, in which a beam of light propagates without changing its transverse profile, occurs when optical non-linearity compensates normal diffraction in the medium. Normally, soliton generated by Kerr effect required optical power as high as few MW. Recently, it was found that photorefractive spatial soliton can be excited at a reasonable optical power within 100 micro-watts that makes soliton a realistic application for devices operation and increases its research interest in photonics devices. In this project, a circular ring resonator with two Y-output couplers had been fabricated to study the output coupling variation of the circular ring resonator due to the generation of the spatial soliton. In addition, an optical-optical switch based on this soliton waveguide had demonstrated. The results can provide an essential references to the development of photonic devices by using solitons.
