Soliton blue-shift in tapered photonic crystal fiber
S. P. Stark, A. Podlipensky, P. St. J. Russell
We show that solitons undergo a strong blue shift in fibers with a dispersion landscape that varies along the direction of propagation. The experiments are based on a small-core ph…
Nonlinear wavelength conversion in photonic crystal fibers with three zero dispersion points
S. P. Stark, F. Biancalana, A. Podlipensky +1
In this theoretical study, we show that a simple endlessly single-mode photonic crystal fiber can be designed to yield, not just two, but three zero-dispersion wavelengths. The pre…
Multiple hydrodynamical shocks induced by Raman effect in photonic crystal fibres
Claudio Conti, Sebastian Stark, Philip St. J. Russell +1
We theoretically predict the occurrence of multiple hydrodynamical-like shock phenomena in the propagation of ultrashort intense pulses in a suitably engineered photonic crystal fi…
Emergence of geometrical optical nonlinearities in photonic crystal fiber nanowires
Fabio Biancalana, Truong X. Tran, Sebastian Stark +2
We demonstrate analytically and numerically that a subwavelength-core dielectric photonic nanowire embedded in a properly designed photonic crystal fiber cladding shows evidence of…
