Paper Abstract

We numerically demonstrate the supercontinuum (SC) generation in a novel chalcogenide As2S5 nanowire embeddedcore into Tellurite photonic crystal fiber (PCF). This hybrid As2S5-tellurite small core PCF has a pitch of 0.7 μm and air hole diameter of 0.2 μm. It exhibits a zero dispersion wavelength (ZDW) of 3.25 μm with an overall highly engineered group velocity dispersion (GVD) shifted to the mid-IR wavelengths region. By injecting 100 fs hyperbolic-secant input pulses delivered by available tunable optical parametric oscillator (OPO) system at the pump wavelength of 3.389 μm, we obtain a broadband coherent mid-IR SC generated in only 1 mm-long PCF with a peak power of 8.8 kW. An ultralarge mid-IR bandwidth extending from 1000 to 7200 nm is generated with more than 60% of the total power which is available beyond 3 μm. The proposed hybrid PCF structure shows to be very promising for designing new compact, stable and powerful SC fiber laser sources in the long mid-IR wavelength region.
