Abstract

A new design of aperiodic As2Se3-based chalcogenide photonic crystal fibers (PCF) is proposed in order to obtain broadband, mid-IR, and coherent supercontinuum (SC) sources. The proposed fibers possess an ultra-flattened dispersion curve over a wide wavelength range. The significance of this work is that it provides a new type of midinfrared SC source with flat shape, broadband and high coherence properties by femtosecond pumping the As2Se3-based PCF. The generated SC in the designed fibers cover a broadband range extending from 2 μm to more than 8 μm with a low input energy of 120 pJ and a short fiber length of 16 mm. In this context, many applications can be performed such as fiber lasers, pulse compression and multi-wavelength optical sources in the mid-infrared region.
