Hollow-core photonic crystal fibres for gas-based nonlinear optics

Russell, P. St. J.; Holzer, P; Chang, Wonkeun; Abdolvand, A.; Travers, J C

Description

Unlike the capillaries conventionally used for gas-based spectral broadening of ultrashort (<100 fs) multi-millijoule pulses, which produce only normal dispersion at usable pressure levels, hollow-core photonic crystal fibres provide pressure-adjustable normal or anomalous dispersion. They also permit low-loss guidance in a hollow channel that is about ten times narrower and has a 100-fold-higher effective nonlinearity than capillary-based systems. This has led to several dramatic results,...[Show more]
