Abstract

In this paper, we report analysis, design, and numerical modeling of mid-infrared supercontinuum generation across 2-15 μm molecular “fingerprint region” using a new design of triangular-core graded-index photonic crystal fiber (PCF) pumped with 50 fs laser pulses of peak power of 3.5 kW at 4.1 μm. ...
