Abstract
In this Letter, we numerically simulate the generation of a 1–15 μm mid-infrared supercontinuum (SC) from a highly nonlinear Ge11.5As24Se64.5-based photonic crystal fiber (PCF). This ultra-broadband SC is achieved in a 100 mm long PCF pumped using 85 fs laser pulses operated at 3.1 μm and a peak pulse power of 3 kW. The proposed design offers a flat dispersion profile with two zero dispersion wavelengths. This broad and flat dispersion profile of the Ge11.5As24Se64.5 PCF, combined with the high nonlinearity (2474 W−1 km−1), generates an ultra-broadband SC.

Photonic crystal waveguides in chalcogenide glasses

Marcel Spurny
TL;DR: In this paper, the dispersion-engineered slow light photonic crystals in chalcogenide glasses have been used to enhance low power nonlinear operation, and a passive all-optical regenerator is proposed by integrating a slow-light photonic crystal waveguide with a band-pass filter based on coupled ring resonance.
