3D-printed terahertz Bragg fiber

Abstract

In this paper we demonstrate the terahertz propagation in Bragg fiber manufactured through rapid prototyping technique using low cost 3D printer. The fiber was numerically and experimentally characterized using software based on beam propagation method (BPM) and a terahertz time domain spectrometer (THz-TDS). The transmission structures indicate a good agreement between numerical and experimental data.
