A modified single-polarization THz fiber with epsilon-near-zero (ENZ) material

A modified single-polarization THz fiber with epsilon-near-zero (ENZ) material

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...
