對稱以及非對稱鋸齒狀長週期光纖光柵之新製法及其光學特性

A New Fabrication Method of Symmetric and Asymmetric Corrugated Long Period Fiber Gratings and Their Optical Characteristics

指導教授 : 王倫

摘要


1999年我們研究小組提出的鋸齒狀長週期光纖光柵 (corrugated long period fiber grating) 克服了傳統需要先有感光光纖以曝光來製作長週期光纖光柵的限制,並且鋸齒狀長週期光纖光柵具有了耦合強度跟光共振條件皆可調的特性。之後,在2006及2007年,我們研究小組另提出一個利用光學微影製程,來製作對稱以及不對稱長週期光纖光柵的新方法提出。然而,這樣的製作方法不僅價格昂貴,而且費時。 在本論文中,我們提出一個新的製作方式結合了熱壓技術以及壓印微影術來製作包括對稱型以及非對稱型的鋸齒狀長週期光纖光柵。此外,藉由這樣的製作方式,我們可以控制非對稱性的程度。此製作方式的優點是可縮短製程時間。以此製作方法製作所得之鋸齒狀光纖光柵的特殊光學特性也會在本論文中討論。

並列摘要


The corrugated long period fiber gratings (LPFGs) reported by our group in 1999 overcome the limitation of conventional fabrication methods which in most cases require photosensitive fibers for making conventional LPFGs. In addition, the corrugated long period fiber gratings possess the characteristics of tunable coupling strength and resonant conditions. In 2006 and 2007, new methods of fabricating symmetric and asymmetric LPFGs by the use of photolithography were reported also by our group. However, this method might be expensive and time consuming. In this thesis, we propose a new method by the use of hot embossing and imprint lithography for fabricating corrugated LPFGs, including symmetric and asymmetric ones. In this method, we can control the asymmetry. Such a method offers the advantage of shortening processing time. The unique optical characteristics of corrugated LPFGs are also discussed in this thesis.
