本論文是探討一種特殊型態的光纖光柵謂之為超結構型光纖光柵。因光纖光柵在光纖通訊網路中,扮演非常重要的角色,為最具潛力與最有發展的光纖被動元件之一,我們藉由理論推導與計算,以及實際的製作量測,再將其與理論計算值分析比較以完成高品質的超結構型光纖光柵,另外也將其應用在光纖感測器,以獲得可同時量測溫度與應變參數的優點。
超結構型光纖光柵具有多波道的特性,此特性不但可取代需串接多個各別寫製的光柵才能形成的多波道,也簡化了寫製時的複雜度。同時我們能依系統的需要而設計出符合系統規格的超結構型光纖光柵,如應用在DWDM系統,將可改善系統的複雜度與成本。另外,由於超結構型光纖光柵是結合短週期光柵與長週期光柵於一體的光柵,若將其應用在光纖感測器方面則可同時量測溫度與應變之物理量,以便簡化感測器的設計與改善系統效能。
The content of this thesis is to investigate a special type of fiber gratings, which is called superstructure fiber Bragg grating (SFBG). Due to the fiber grating acting on very important role in optical fiber communication systems it may become one of the most potential passive fiber components. By means of the basic principles and theoretical calculations we have accomplished the practical fabrication and it is a good agreement with theoretical calculations. For another application it can be used in fiber sensors to measure strain and temperature parameters simultaneously.
SFBG possesses the characteristic of multi-channel that replace a serial multiple fiber gratings. We can design a SFBG to satisfy system requirements according to DWDM specifications and to improve design complications for obtaining a better performance. Owing to a SFBG composed of a fiber Bragg grating and a long period grating, strain and temperature parameters can be measured simultaneously. This performance can simplify the design of fiber sensors for improving the sensor system.
