Investigation of Highly Broadb and Supercontinuum Generation in a Suspended As2Se3 Based Ridge Waveguide
n this paper, the generation of a highly broadband supercontinuum spectrum has numerically been investigated in a suspended As2Se3 based ridge waveguide. By changing the dimensions of the proposed waveguide, the dispersion has been engineered to achieve a suitable profile with the two zero-dispersion wavelengths as well as the lower magnitude and flat anomalous dispersion regime. Due to the high refractive index contrast between the core and cladding, the propagated light has been highly confined in the core and as a result, a high optical nonlinear coefficient has been obtained. Simulation results show that when the pump pulses with a width of 100 fs and peak power of 1KW at the wavelength of 2150 nm are injected into the designed
