Abstract

A highly birefringent square lattice terahertz (THz) photonic crystal fiber (PCF) coated with epsilon-near-zero (ENZ) material and doped with gain material is proposed for single polarization propagation. Due to introduction of the ENZ rings into square lattice, the large loss difference between the x-polarization mode and all other modes is obtained. The loss of the x-polarization mode is compensated by doping the core area with gain material. The single polarization PCF obtains a loss difference better than 13.2 dB/cm in the frequency range of 0.960–1.307 THz (bandwidth of 0.347 THz). This proposed single polarization THz PCF has some potential applications in coherent THz communication or polarimetric fiber sensor systems.
