光纖光柵之研製及其在DBR光纖雷射與光纖光柵共振器之應用

Abstract

在本論文中我們研究光纖光柵的理論、製作、及應用。在實驗上我們成功 的利用相位光罩製作出具有高反射率的光纖光柵，並利用此光纖光柵製作 出了DBR光纖雷射。此種雷射具有穩定、頻寬窄和體積輕巧的特性，可作 為光纖通訊系統或光纖感測器的理想光源。我們也探討了移相光纖光柵共 振器的原理和製作方法，成功地製作出四分之一波長移相光纖光柵共振器 ，並且量測了這種共振器結構的共振特性；此種共振器結構將可供為製作 窄頻濾波器或是DFB光纖雷射之用。 In this thesis we study the theory, fabrication, and applicationsof fiber gratings. We have successfully fabricated high-reflectivityfiber gratings using the phase mask approach and used them to buildEr DBR fiber lasers. Such lasers are very compact, stable, and have a very narrow linewidth. They are suitable light sources for fibercommunication systems and fiber sensors. We have also successfully fabricated phase-shifted fiber grating resonators and measured theirresonant characteristics. Such a kind of resonators can be used fornarrow-band filtering or to build DBR fiber lasers.
