“…From the NL-1050-NEG-1 we achieved smooth Group Delay distribution without any discontinuities. The benefit of the broadband all-normal dispersion supercontinuum is the possibility to compress the pulse to very short durations [18], which we also presented in [19]. Crossing the ZDW during the broadening of the spectrum in the case of LMA-PM-5 fiber dramatically changes the characteristic of the output supercontinuum pulse.…”

Ultra broadband supercontinuum pulses are commonly used as a source of different wavelengths from a wide spectral bandwidth or as a source of very short pulses. However the processes responsible for wide spectral broadening are still under investigation. In this paper we examine the temporal and spectral characteristics of the pulses broadened upon propagation in the highly nonlinear photonics crystal fibers with different dispersion profiles. Generated supercontinuum pulses were experimentally characterized using cross-correlation frequency resolved optical gating technique. Full Text: PDF ReferencesM. Bradler, P. Baum, and E.

“…The VECSEL wavelength was in the normal dispersion regime for both fibers, which have a dispersion minimum at 1064 nm and a zero dispersion point at 1040 nm respectively. Dispersion curves of the two fibers can be found in references [16] for the UoB fiber and [17] for the NKT fiber. A transmission of 45% was achieved in the case of the UoB fiber, corresponding to an output power of 650 mW, but thermal issues with the fiber coupling limited the power output from the NKT fiber to 350 mW.…”

“…The broadening mechanism in the case of short pump pulses mainly results from soliton dynamics and the breakup of the injected pulses through soliton fission is very sensitive to shot-to-shot input pump pulse to pulse intensity fluctuations [5]. These intensity fluctuations limit the signal-to-noise ratio in various applications including optical coherence tomography and frequency metrology [6]. The noise and amplitude fluctuation induced in spectral components can be reduced significantly by suppressing the soliton fission during SC evolution by using short waveguide design [7].…”

This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract-We numerically study the dispersion-engineered chalcogenide photonic crystal fiber (PCF) which allows us to generate ultraflat broadband supercontinuum (SC) spectra in allnormal dispersion regime. A 1-cm-long chalcogenide hexagonal PCF made using Ge11.5As24Se64.5 glass pumped at 1.55 µm produced a SC bandwidth 700 nm at a peak power of 1 kW. By shifting pump at 2 µm, SC spectra can be extended with a bandwidth of 1900 nm at the same peak power level. In both cases, nonuniform spectral power distribution observes over the entire output bandwidth owing to the lower dispersion slop on the long wavelength side of the dispersion curve. To spanning SC further in the mid-infrared as well as to reduce the spectral asymmetry, we optimize another design for pumping at 3.1 µm in such a way that the pump source can be employed vicinity to the peak of the dispersion curve. Employing the largest pump peak power up to 5 kW, SC can be extended up to 6 µm (1.5 octaves) and the power distribution among the spectral components over the entire SC bandwidth can be improved significantly by this design. To enhance the spectral flatness, we optimize a second PCF geometry by reducing its pitch length and it is possible to obtain ultraflat coherent SC spanning from 2 µm to 5.5 µm (>1 octave) by this structure maintaining nearly symmetric power distribution between both side of its spectral components.
