Design of subwavelength optical fibre for low-loss Terahertz transmission

N. F. Ren, M.-Y. Chen, B. Sun, L. Ge

Abstract

A low-loss Terahertz (THz) transmission optical fibre with a subwavelength core is reported in this article. The main fibre is composed of a subwavelength solid polymer core and a tube. The tube is used to prevent the extending of THz wave to the external environment. Two solid ends are introduced to suspend the subwavelength core in the air. The solid fibre ends are found have low splicing losses with the main fibre. The proposed fibre provides a simple technique for the transmission of THz wave in a short distance.
