非线性系数可达83.3W-1km-1

限制损耗低于10-9 dB/m

有效模场面积仅为1.46μm2

该PCF的高非线性效应与低限制损耗特性可以应用于超连续谱产生、非线性光学和光通信系统等领域。

Abstract

A simple-structured four-hole composite photonic crystal fiber with high nonlinearity and low confinement losses is proposed.Its air-hole diameter d =0.2μm and pitch of holesΛ =1.8μm.The numerical calculation results show that when a unique four-hole unit structure is introduced into the cladding region

the nonlinear coefficient is up to 83.3 W-1km-1 and the confinement loss lower than 10-9 dB/m at the wavelength of 1.55μm

and the corresponding effective mode field area is only 1.46μm2.These characteristics can be used in supercontinuum generation

nonlinear optics and optical communication systems.
