Refraction of a Gaussian Seaway
, 2008 Refraction of a Longuet-Higgins Gaussian sea by random ocean currents creates persistent local variations in average energy and wave action. These variations take the form of lumps or streaks, and they explicitly survive dispersion over wavelength and ...

Complex nonlinear refractive index of DNA
Chemical Physics Letters, 2006 Abstract Femtosecond Z-scan technique was used to determine the dispersion of the complex cubic nonlinear susceptibility (related to the nonlinear refractive index n 2 and the two-photon absorption coefficient β 2 ) of deoxyribonucleic acid (DNA) in the range of wavelengths from 530–1300 nm. The nonlinear refractive index of DNA varies from ≈ 2 ×

Optical bistability in a nonlinear photonic crystal waveguide notch filter [PDF]
, 2000 Optical bistability occurs when the effects of nonlinear behaviour of materials cause hysteresis in the transmission and reflection of a device. A possible mechanism for this is a strong dependence of the optical intensity on the index of refraction, e.g.

Nonlinear refraction in semitransparent pyrolytic carbon films
, 2012 We report on Z–scan measurements of the nonlinear refractive index of semitransparent pyrolytic carbon films. The nonlinear refractive index of the film is as high as 8.23 × 10−9 cm2/W and shows a non–monotonous dependence on the film thickness.
