Abstract Usage of the ”Cabaret” explicit-implicit numerical scheme is proposed to model field dynamics both in microcavities and fibre cavities. Two opposite running waves are investigated with a number of the nonlinear effects included in the model, with potential to include more if necessary.

We develop a computational approach for ultrafast nano-optics based on first-principles time-dependent density functional theory. Solving Maxwell equations for light propagation and time-dependent Kohn-Sham equation for electron dynamics simultaneously, intense and ultrashort laser pulse interaction with a dielectric nano-structure is described taking full account of nonlinear effects. As an illustrative example, irradiation of a pulsed light on silicon nano-sphere system is presented.

We want to study the influence of the quantum vacuum on light propagation. At first, by working in the standard linear quantum theory of the electromagnetic fields, it is shown that the electric permittivity and the magnetic permeability of the vacuum medium are changed; but, the resulting speed of light is not modified. Then, taking into account nonlinear effects by considering the Euler–Heisenberg Lagrangian, the corresponding zero point (vacuum) energy and the resulting modification of the speed of light are found up to the first nonvanishing correction.

An analytic expression describing two-wavelength light propagation through an organic photoreversible photochromic Azo and Stilbene-like molecular media characterized by a strong nonoverlapping absorption by the two chromophore isomers has been derived. An analysis of the transmission coefficients for the Trans and Cis modulation modes has shown linear dependence on the pump intensity accompanied by self modulation slope dependence. In addition, the wavelength dependence of the modulation strength and the resulting inverse relationship of the pump intensity as a function of the absorption cross-section has been presented. Large constrast ratios have been obtained for rather low pump and read-out intensities of the order of a hundred microwatts per centimeter square and less. Such optimal working conditions provide a very attractive characteristic for an OASLM based on photoreversible photochromic organic molecular systems.
