Topas Based Low Loss Suspended Porous Core Single Mode Photonic Crystal Fiber for THz Wave Propagation

A novel photonic crystal fiber (PCF) with rectangular shaped core is presented in this design. The structural properties of the proposed fiber are described by the Finite Element Method (FEM). From the proposed fiber, it is shown that the PCF indicates extremely low effective material loss (EML) of 0.027 cm

at 1.0 THz for optimum fiber parameters and a low dispersion at broad frequency range. The structural design of the proposed fiber is very simple and very easy to fabricate because of its simplicity. In this study other important optical guiding properties such as power fraction, v-parameter also discussed thoroughly. Due to have very low loss this proposed fiber would be very effective for the application of THz regime.
