Mid-infrared Supercontinuum Generation in AS2Se3 Glass Based C2H5OH Filled Square Photonic Crystal Fiber

Abstract

We arithmetically demonstrated the ultrawideband mid-infrared supercontinuum generation (SCG) in As2Se3 based square photonic crystal fiber (S-PCF) with first inner ring air holes filled with C2H5OH liquid. From the result of simulations, it is seen that up to 7500 nm SC spectra is achieved in the case of without liquid S- PCF by using an optical pulse of 10 kW peak power with 50 fs input at 2450 nm. In addition, C2H5OH liquid-filled S-PCF offers SC broadening up to 9000 nm by employing an input pulse of 10 kW peak power (Ppeak). In the areas of early awareness of cancer, food quality checking and gas sensing, the proposed technology could be a suitable candidate.
