Abstract

The ultrabroadband mid-infrared (MIR) supercontinuum (SC) generation using dispersion-tailored Ge11.5As24Se64.5 chalcogenide (ChG) glass rib-waveguide has been investigated numerically. An air-clad 1-cm-long rib-waveguide employing MgF2 glass for its lower cladding shows that an ultrabroadband MIR SC spanning from 1.8 to 8 μm and extending over more than 2 octave could be generated with a relatively low peak power of 0.5 kW pumped at a wavelength of 3.1 μm. Our estimated bandwidth is the largest reported so far for SC generated using ChG rib-waveguide pumped at a wavelength of 3.1 μm with a low peak power of 0.5 kW. We carry out simulations by varying peak power ranges between 0.1 and 3 kW. Our analysis through rigorous numerical simulations show that SC can be extended further into the MIR up to 10 μm using the same pump pulses with a relatively modest peak power of 3 kW.
