Supercontinuum generation in organic liquid-liquid core-cladding photonic crystal fiber in visible and near-infrared regions

Abstract

In this paper, we propose a liquid core-cladding photonic crystal fiber (PCF), which is engineered with different available organic optofluidics, to generate supercontinuum in the visible and near-infrared regimes by using the symmetrized split-step Fourier method. Simulations reveal that in response to launching 50 fs input pulses of 10 kW peak power, centered about λ0=1032 and 1560 nm, into a 10 mm long liquid core-cladding PCF, maximum 2 μm supercontinua from 500 to 2500 nm can be achieved. Our numerical study is important for the new field of visible and near-IR supercontinuum generation in liquid-core optical fibers.
