摘要

摘要提出了一种新型的中红外Ge20Sb15Se65硫系单极化单模光子晶体光纤(PCF)，该光纤具有矩形点阵圆形气孔。利用时域有限差分(FDTD)方法分析了SPSM在3 μm~8 μm中红外波段的带宽、约束损耗和非线性特性。分析了不同几何参数对SPSM-PCF性能的影响。所有数值计算结果表明，在优化几何参数的情况下，所提出的PCF可以提供超过2.3814 μm的SPSM区域，并且具有3,705 w−1 km−1的高非线性。因此，这种SPSM-PCF将成为中红外光子的理想候选者。

Design of a Novel Mid-Infrared Single-Polarization Single-Mode Photonic Crystal Fiber with Low Loss, High Nonlinearity, and Large Bandwidth

ABSTRACT A novel mid-infrared Ge20Sb15Se65 chalcogenide-based single-polarization single-mode (SPSM) photonic crystal fiber (PCF) with rectangular latticed circular air holes is proposed. The properties of SPSM bandwidth, confinement loss, and nonlinearity are analyzed in the 3 μm~8 μm mid-infrared region using the finite -difference time-domain (FDTD) method. The influences of different geometrical parameters on the properties of SPSM-PCF are analyzed. All numerical computational results reveal that for the optimized geometrical parameters, the proposed PCF can deliver a SPSM region of more than 2.3814 μm with high nonlinearity of 3,705 w−1 km−1. Therefore, such a SPSM-PCF will become an excellent candidate for mid-infrared photonic.

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
