TL;DR: In this paper, single-shot supercontinuum spectral interferometry was used to measure the nonlinear index of refraction due to the optical Kerr effect in water at both 815 and 407 nm, with pump pulse lengths of ∼90 and ∼250
Abstract: Single-shot supercontinuum spectral interferometry was used to measure the nonlinear index of refraction due to the optical Kerr effect in water at both 815 and 407 nm, with pump pulse lengths of ∼90 and ∼250 fs, respectively. Knowledge of the nonlinear index at 407 nm allows pulse tailoring to achieve remote underwater pulse compression and self-focusing.

TL;DR: In this paper, it was shown that supercontinuum generation in a fiber containing a Bragg grating exhibits >10× enhancement near the Bragg resonance wavelength, and that the grating dispersion exceeds the waveguide dispersion over a bandwidth far in excess of its photonic band gap.
Abstract: We show that supercontinuum generation in a fiber containing a Bragg grating exhibits >10× enhancement near the Bragg resonance wavelength. We also show that the grating dispersion exceeds the waveguide dispersion over a bandwidth far in excess of its photonic band gap. The observed enhancement is consistent with nonlinear Schrodinger equation simulations of the supercontinuum formation that combine grating and waveguide dispersion.

TL;DR: In this article, the authors investigate theoretically and experimentally the process of supercontinuum generated in sub-wavelength waveguides and find that supercontinuities generated in these photonic nanowires are increasingly blue-shifted from the pump wavelength for decreasing minimum core diameters.
Abstract: We investigate theoretically and experimentally the process of supercontinuum generated in sub-wavelength waveguides. We observe experimentally that supercontinuum generated in these photonic nanowires is increasingly blue-shifted from the pump wavelength for decreasing minimum core diameters. We also find the spectral features are sensitive to the specific nanowire profile. Numerical simulations using the nonlinear envelope equation show that accurate modeling requires consideration of the nonlinearity and full dispersion along the entire nanowire profile as well as a wavelength dependent loss. Specifically, the blue-shifting is found to result from an increasing loss for wavelengths larger than the core diameter.
