Simulation of a highly birefringent photonic crystal fiber in terahertz frequency region

A Reconfigurable Surface-Plasmon-Based Filter/Sensor Using D-Shaped Photonic Crystal Fiber

“…Photonic crystal fibers (PCF) are a new type of fiber that has a flexible structure and various unique features, such as high nonlinearity [1], engineered dispersion profile over the region of interest [2,3], high birefringence [4], endless single mode, low transmission loss [2][3][4][5] and easy filling of materials in fiber [6][7][8]. PCF has been extended to plasmonic devices by filling them with various metals, such as gold [9][10][11][12][13], silver [14,15], copper [16] and titanium [17].…”

Fibre devices enabled by hollow core fibre technology

“…And as indicated in [49], since the shape of the struts composing the core and the cladding boundary determines the confinement loss, the TLFs exhibit much better performance in terms of the loss level. Benefited from their unique properties of low transmission loss, broad transmission band, low nonlinearity, low dispersion, high material damage threshold and low data transmission latency, the HAFs see numerous research interests in the following two decades till now in many studies and application areas, such as gas species and pressure sensing, mechanical sensing, light delivery at THz frequency, high nonlinearity control, DNA detection, to name a few [17,[50][51][52][53].…”

“…Aiming at the polarising features, a Kagome fibre with an elliptical porous core was theoretically demonstrated with 10 −2 order of birefringence at terahertz frequencies [52].…”
