Based on the requirement and target of the projects, firstly, pcf bragg grating are investigated theoretically and experimentally. moreover, the effects of filling high refractive index material ( nematic liquid crystal, nlc ) in pcfs on the transmission mechanism and propagation properties are studied by using plane - wave method and finite - element method ( fem ), farther, several novel pcfs are proposed and designed. lastly, we propose and demonstrate a clad - pumped er3 + / yb3 + - codoped fiber laser, which integrate all performances of broad - band tunable wavelength, uniform output power spectrum, high repeat frequency and high average power to together
本論文選題于國家973 、 863以及國家自然科學基金等項目，結合課題的要求和主要目標，在對光子晶體光纖（ pcfs ）傳輸特性研究的基礎上，首先對光子晶體光纖光柵進行了理論和實驗研究;然後，採用平面波展開法和有限單元法分析了在光纖的空氣孔中填充高折射率液晶對光纖傳導機制和傳輸特性的影響，提出並設計了幾種新型光子晶體光纖;最後，提出並研製成功連續可調諧、輸出功率譜均衡的全光纖化、高功率包層泵浦鉺鐿共摻光纖激光器實驗樣機。 -
Recently it has also been applied to rf ( ratio frequency ) fields, and valuable achievements have been reached. ‘ fractal ’ has space filling ability and self - similarity ability. ‘ fractal ’ is a recursively generated structure by iterated function systems. it has a fractional dimension and possesses a self - similarity property. the concept of a ‘ fractal ’ has been applied to antenna design in order to reduce the size of antenna and obtain multi - band frequency operation
分形具有空間填充能力和自相似性，分形是通過迭代函數系統產生的具有自相似性的分數維結構，分形的概念可用於天線設計以實現天線的尺寸減縮和多頻特性，這在軍用和民用方面都有著非常廣泛的應用前景。 -
