本論文主要目的在研究並實現波長1.55微米附近的光經過單模光纖光柵Fabry - Perot﹙F-P﹚干涉器後具有光選擇和光穿透特性。我們利用波長248nm的準分子雷射（Excimer Laser）經過相位光罩（Phase Mask）後繞射並產生雙光束干涉，在摻鍺的感光光纖上寫製光柵。由於傳統光纖光柵（Fiber Bragg Grating）是使用其反射光譜，所以我們在此提出一個新方法利用Fabry-Perot型的多光束干涉特性，產生特定波長穿透的窄帶率光器（Narrow Band-Pass Filter），以期將它用在高密度多波道光纖通訊（DWDM）中。我們對一個共振腔的F-P光纖光柵設計及製作，並改善其光譜特性，再加以研究比較F-P 光纖光柵與傳統反射式光纖光柵在受溫度及壓力後的特性，可提供將來對元件的應用及受環境影響的補償。 The main destination of this thesis is to investigate and fabricate single mode Fabry-Perot interferometer fiber for near 1.55 um wavelength. We use a wavelength 248 nm excimer laser to explore the Ge-dopped photo-sensitive fiber. The light diffraction across phase mask and produce two beam interference. The traditional Fiber Bragg Grating can reflect selected wavelength. In this thesis we use Fabry-Perot type to fabricate Fiber Bragg Grating to transmit a selected wavelength for Dense Wavelength-Division Multiplexing system. By comparing the effects of heat and stress to the traditional Fiber Bragg Grating and Fabry-Perot type Fiber Bragg Grating, we can provide the reference investigated here is very useful for the compensation when using in the outside environment
