摘要

本文研究了独特的嵌入纳米孔的光子晶体光纤（PCF）结构。嵌入的纳米孔已经填充了不同的醇基材料，如丁醇、乙醇、甲醇和丙醇。对这些结构的研究表明，在可见光到远红外区域，零色散是平坦的。模拟的PCF结构报告了10-8dB/km量级的超低限制损耗。设计的PCF有望在1335nm波长下产生3000W-1Km-1的大非线性系数。对产生超连续谱的光纤进行了数值模拟。已经使用了持续时间为50fs的低功率泵浦脉冲。当光纤长度为15cm，脉冲峰值功率为1kW、2kW、5kW和10kW时，超连续谱加宽分别约为607nm、908nm、1987nm和2405nm。

Flattened zero dispersion Photonic crystal fibers with embedded nano holes and ultra low confinement loss for supercontinuum generation

In this paper unique photonic crystal fiber (PCF) structure with nanoholes embedded have been studied. Embedded nanoholes have been filled with different materials of alcoholic groups like butanol, ethanol, methanol and propanol. Investigations of these structure shows flattened zero dispersion in visible range to far infrared regions. Simulated PCF structure reports ultra-low confinement loss of the order of 10-8 dB/km. Designed PCF promises to give large nonlinear coefficient of 3000 W-1Km-1 at 1335nm wavelengths. Numerical simulation of the fiber for the generation of supercontinuum generation (SCG) has been performed. Low power pump pulses of 50fs duration have been used. With a fiber of length of 15cm and pulses of 1kW, 2kW, 5kW and 10kW peak power, supercontinuum broadening of about 607nm, 908nm, 1987nm and 2405nm respectively.
