In 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 راهنمای موج با طول 0.8 میلی متر ، ابرمتنت تولید شده را می توان در محدوده طول موج از 1.4 تا 18μm گسترش داد. چنین ساختار راهنمای موج برای منابع فوق پیوسته مادون قرمز درون تراشه که در بسیاری از زمینه ها مانند توموگرافی انسجام نوری ، اثر انگشت ، طیف سنجی مولکولی و غیره بسیار مهم است بسیار قابل استفاده است
