Abstract

This paper presents a highly negative dispersion-compensating photonic crystal fiber (DC-PCF) with multiple zero dispersion wavelengths (ZDWs) within the telecommunication bands. The multiple ZDWs of the PCF may lead to high spectral densities than those of other PCFs with few ZDWs. The full-vectorial finite element method with a perfectly matched layer (PML) is used to investigate the optical properties of the PCFs. The numerical analysis shows that the proposed PCF, i.e., PCF (b), exhibits multiple ZDWS and also achieves a high negative chromatic dispersion of −15089.0 ps/nm·km at 1.55 μ m wavelength, with the multiple ZDWs occurring within the range from 0.8 to 2.0 μ m range. Other optical properties such as the confinement loss of 0.059 dB/km, the birefringence of 4.11 × 10 − 1 , the nonlinearity of 18.92 W − 1 k m − 1 , and a normalized frequency of 2.633 was also achieved at 1.55 μ m wavelength. These characteristics make the PCF suitable for high-speed, long-distance optical communication systems, optical sensing, soliton pulse transmission, and polarization-maintaining applications.

多个零色散波长的高负色散补偿光子晶体光纤的设计与理论分析

本文提出了一种在通信频带内具有多个零色散波长（ZDW）的高负色散补偿光子晶体光纤（DC-PCF）。与具有少量ZDW的其它PCF相比，PCF的多个ZDW可导致高光谱密度。采用具有完全匹配层的全矢量有限元方法（PML）研究了PCF的光学特性。数值分析表明，所提出的PCF，即PCF（b），表现出多个ZDWS，并且还实现了−15089.0的高负色散 1.55时的ps/nm·km μm波长，多个ZDW出现在0.8到2.0的范围内 μm范围。其他光学特性，如0.059的限制损耗 dB/km，双折射4.11×10−1，非线性18.92 W−1 k m−1，并且在1.55时也实现了2.633的归一化频率 μm波长。这些特性使PCF适用于高速、长距离光通信系统、光学传感、孤子脉冲传输和保偏应用。
