Abstract:	隨著人類社會信息化速率的加快，對通信的需求也成高速增長的趨勢，由於光纖傳輸技術不斷的發展，在傳輸領域中，光傳輸已佔主導地位。光纖存在巨大的頻寬資源和優厚的傳輸性能，是實現高速、大容量傳輸的理想傳輸媒介，而近年來，長距離的高密度分波多工系統中採用了摻鉺光纖放大器的技術，使光纖衰減對傳輸距離的限制得以解決，但因光傳輸速率的大為提升，使得整個傳輸線路的總色散也隨之增加，造成信號脈衝變形，對於高速傳輸系統而言是一個主要的限制，因此色散補償的管理技術將是一需克服之技術。本論文利用光學薄膜設計一種反射式的啁啾式共振色散補償濾光片(Chirped-Cavity dispersion compensator filter)，設計中結合了Gires-Tournois干涉濾光片及Chirped濾光片的優勢，使其具有更彈性的頻寬及群速度延遲色散值，且有高度潛力的發展性。 As the amount of information rate for human using grows up, the requirement of signal communication also trends to increase. Due to the technology of optical fiber transmission development unceasingly, optical transmission occupies the leading role in transmission domain. However optical fiber not only has natural resources of enormous bandwidth, but also has munificent transmission properties. It is an idea transmission medium to carry out high speed and large capacity. Nowadays, long distance of dense wavelength division multiplexing (DWDM) system has already adopted the technology of Erbium doped fiber amplifier, which provides a solution to the limitation of fiber loss. When the transmission rate promotes enormously, total dispersion effect of all line of communication becomes serious and signal pulse is out of shape. Therefore dispersion effect is a mainly limitation of high speed transmission system and the manage technology of dispersion compensation is a problem needs to be overcome. This study utilizes optical thin film to design a reflective Chirped-Cavity dispersion compensator filter. This design combines the advantage of Gires-Tournois interferometers (GTI) filter and Chirped dielectric mirror (CM) which has flexible bandwidth and group delay dispersion for dispersion compensation. It also has high potential development.
