本論文以中空光纖為基礎,發展兩種全光纖式中空光纖元件並探討其特性。第一為 “色散控制之填液式中空光纖電弧長週期光纖光柵”,第二部份為 “全光纖式中空光纖Mach-Zender干涉儀”。
在第一部份的實驗中,使用電弧放電製造中空光纖上長週期形狀之輕微形變,再灌入光學折射率匹配油於中空光纖中,製成液態長週期光纖光柵,由於光學液體與一般傳統單模光纖(SMF-28)的纖芯二氧化矽摻鍺之色散特性不同,因此,所製成之長週期光纖光柵也不同,文中分析色散控制之元件特性,並將此元件做溫度調變,測量頻譜響應並與模擬結果做比較與特性分析。
在第二部份的實驗中,使用不同尺寸之中空光纖兩端熔接於單模光纖,製成不同尺寸、不同長度之全光纖式Mach-Zender干涉儀,本研究分析這些中空光纖干涉儀耗散(Leaky)模場之干涉頻譜特性,也量測雷射光經過所發展之元件其光束模場分佈之情形。

This thesis developed and demonstrated two kinds of in-fiber optical fiber devices based on hollow core fibers. The first device is the “Liquid Core Arc-Induced Long-Period Fiber Gratings” and the other is “All-fiber Mach-Zender Interferometer Based on Hollow Core Fibers”.
In the first experiment, an arc-induced long period grating on the hollow core fiber was filled with an optical liquid to form a liquid core arc-induced long-period fiber grating (AI-LPFG). Since the dispersion characteristic of the index matching optical liquid is different with Ge-doped fiber core, diverse optical properties of the proposed device can be demonstrated. Simulated and experimental results show the resonant dips of the AI-LPFG with opposite wavelength shifts when compared to the general LPFG. It would be attributed by the material dispersion control of the liquid on the proposed device.
In the second study, different diameter and length of the hollow core fibers have been fused with single mode fibers to form the proposed all–fiber Fiber Mach-Zehnder Interferometers (FMZI). The leaky modes interference of the proposed device has been investigated. Near filed of the laser beam profiles are also measured by a CCD camera beam profiler to analyze the mode patterns of the different FMZIs.
