Abstract Jute ( Corchorus sp.) is one of the most important sources of natural fibre, covering ∼80% of global bast fibre production 1 . Only Corchorus olitorius and Corchorus capsularis are commercially cultivated, though there are more than 100 Corchorus species 2 in the Malvaceae family. Here we d...

We propose a novel design of a slotted core photonic crystal fiber (PCF) that offers ultra low-loss and high birefringence attribute for efficient transmission of terahertz (THz) waves. A finite element method has been used to investigate the modal characteristics of the PCF. Our design incorporates...
