Abstract

A photonic crystal fiber (PCF) structure in Ga–Sb–S-based chalcogenide glass has been designed for nonlinear applications. The propagation characteristics of the designed structure have been investigated by employing COMSOL multiphysics software based on a full-vectorial finite element method. The proposed PCF structure possesses a nonlinear coefficient as high as 14.92 W−¹ m−¹ with the effective mode area of 3.37 μm² at the operating wavelength of 1.55 μm. The proposed structure exhibits a flat and low dispersion value between spectral spanning 2.4 and 2.7 μm with a maximum dispersion variation of 20 ps/nm km. To the best of our knowledge, the PCF design is investigated for first time in Ga–Sb–S-based chalcogenide glass. The structure possesses a zero dispersion wavelength value at 2.6 μm. The structure is a promising candidate for nonlinear applications, such as midinfrared supercontinuum generation, slow-light generation, and midinfrared fiber lasers.
