Paper Abstract

Supercontinuum generation is shown for the first time in a tapered triangular structure photonic crystal fiber with two closely spaced zero dispersion wavelengths where dispersion becomes normal for all guided wavelengths at a certain distance along the taper. The numerical calculation shows an increased bandwidth and a reduced depletion of the pump source when the photonic crystal fiber is tapered. We simulate the propagation of 15 femtosecond pulse with a peak power of 80 kW centered at 808 nm. Both fiber and pump source are commercially available and the improved light source can be used for measuring techniques such as optical coherence tomography and spectroscopy.
