Abstract

This paper presents a novel approach to attain a single-polarization-single-mode (SPSM) photonic crystal fiber (PCF) in the terahertz (THz) regime. An initial circular hole PCF design is modified by introducing asymmetry in the first ring of six air holes in the cladding, i.e., epsilon-near-zero (ENZ) material is introduced into only four of those air holes and the other two remain air-filled but have different diameters. The resulting fundamental X-polarized (XP) and Y-polarized (YP) modes have distinctly different electric field distributions. The asymmetry is arranged so that the YP mode has a much larger amount of the field distributed in the ENZ material than the XP mode. Since the ENZ material is very lossy, the YP mode suffers a much higher loss than the XP mode. Consequently, after a short propagation distance, the loss difference (LD) between the XP and YP modes will be large enough that only the XP mode still realistically exists in the PCF. To further enhance the outcome, gain material is introduced into the core area to increase the LDs between the wanted XP mode and any unwanted higher order (HO) modes, as well as to compensate for the XP mode loss without affecting the LD between the XP and YP modes. The optimized PCF exhibits LDs between the desired XP mode and all other modes greater than 8.0 dB/cm across a wide frequency range of 0.312 THz. Consequently, the reported PCF only needs a length of 2.5 cm to attain an SPSM result, with the unwanted modes being more than 20 dB smaller than the wanted mode over the entire operational band.

摘要

本文提出了一种在太赫兹（THz）波段获得单偏振单模（SPSM）光子晶体光纤（PCF）的新方法。通过在包层中六个空气孔的第一环引入不对称性来修改初始的圆形孔PCF设计，即仅在其中四个空气孔中引入近零介电常数（ENZ）材料，另外两个保持为空气填充但具有不同直径。由此产生的基本X偏振（XP）和Y偏振（YP）模式具有明显不同的电场分布。这种不对称性的安排使得YP模式在ENZ材料中分布的场量比XP模式大得多。由于ENZ材料损耗很大，YP模式的损耗比XP模式高得多。因此，在短传播距离后，XP和YP模式之间的损耗差（LD）将足够大，以至于在PCF中实际上只有XP模式仍然存在。为了进一步增强效果，在纤芯区域引入增益材料，以增加所需的XP模式与任何不需要的高阶（HO）模式之间的LD，同时补偿XP模式的损耗而不影响XP和YP模式之间的LD。优化后的PCF在0.312 THz的宽频率范围内，所需的XP模式与所有其他模式之间的LD大于8.0 dB/cm。因此，所报道的PCF仅需2.5 cm的长度就能实现SPSM结果，在整个工作频段内不需要的模式比所需模式小20 dB以上。
