【摘要】：光子晶體光纖(Phetonie Crystal Fibers,PCFs),又稱為微結(jié)構(gòu)光纖(Mierostruetured Optical Fiber)和多孔光纖(Holey Fibers)。PCFs和傳統(tǒng)的普通光纖在結(jié)構(gòu)上不同,全世界研究人員對它產(chǎn)生了濃厚的興趣。通過前兩章對概念的了解,在第三章中系統(tǒng)的對光子帶隙型和全內(nèi)反射型光子晶體光纖的傳輸特性進行了研究,通過利用RSOFT軟件光光子晶體光纖產(chǎn)生的進行帶隙模擬,并對其結(jié)構(gòu)進行設(shè)計;并通過使用COMSOL軟件對限制損耗進行仿真計算,同時利用軟件對全反射型光子晶體光纖進行仿真。本文在第四章對光子晶體光纖和普通單模光纖的的耦合損耗進行計算并對傳輸損耗和熔接損耗進行實驗測量。通過選用電弧熔接機,對HC-1550和HI-1060兩種光纖利用光源和功率計進行測量,選取合適的熔接參數(shù),將兩種光纖進行熔接。結(jié)構(gòu)顯示,通過優(yōu)化熔接參數(shù)對不同放點強度和不同放點時間熔接時產(chǎn)生的空氣孔內(nèi)部產(chǎn)生的塌陷和模場失配等現(xiàn)象對傳輸損耗和相熔損耗所產(chǎn)生的現(xiàn)象進行解析。
[Abstract]:Photonic crystal fiber (Phetonie Crystal Fibers / PCFs). Also known as microstructured Optical Fibers and porous Fiber Holey Fibers). The structure of PCFs is different from that of conventional fibers. Researchers all over the world are interested in it. Through the understanding of the concept in the first two chapters, the transmission characteristics of photonic bandgap and total internal reflection photonic crystal fibers are systematically studied in chapter 3. The band gap of photonic crystal fiber is simulated by using RSOFT software, and the structure of the optical photonic crystal fiber is designed. And through the use of COMSOL software to limit the loss of simulation calculation. In chapter 4th, the coupling loss between photonic crystal fiber and ordinary single-mode fiber is calculated, and the transmission loss and weld loss are measured experimentally. Through the selection of arc welding machine. The HC-1550 and HI-1060 optical fiber are measured by light source and power meter. The appropriate welding parameters are selected and the two fibers are fused. The structure is displayed. By optimizing welding parameters, the phenomena of transmission loss and phase melting loss caused by air hole collapse and mode field mismatch caused by different discharge strength and time are analyzed.
