Supercontinuum generation in photonic crystal fiber

A topical review of numerical and experimental studies of supercontinuum generation in photonic crystal fiber is presented over the full range of experimentally reported parameters, from the femtosecond to the continuous-wave regime. Results from numerical simulations are used to discuss the temporal and spectral characteristics of the supercontinuum, and to interpret the physics of the underly...

Supercontinuum Generation in a Highly Nonlinear Chalcogenide/ MgF2 Hybrid Photonic Crystal Fiber

In this paper, we report the numerical analysis of a photonic crystal fiber (PCF) for generating an efficient supercontinuum medium. For our computational studies, the core of the proposed structure is made up of As2Se3 and the cladding structure consists of an inner ring of holes made up As2Se3 and four outer rings of air holes in MgF2. The proposed structure provides excellent nonlinear coeff...

On the interferometric coherent structures in femtosecond supercontinuum generation

Mechanism of SC generation is not fully understood as at such high laser powers interplay among several competing mechanisms occurs. Self-phase modulation (SPM) [2, 5, 7, 14, 15] associated with self-focusing is considered to be the trigger for the drastic broadening of ultrashort pulses. The intensity-dependent “induced Kerr-nonlinearity” of the dielectric medium and the beam shape causes the ...
