Power transfer between neighboring planar waveguides

Radiation induced force between two planar waveguides

We study the electromagnetic force exerted on a pair of parallel slab waveguides by the light propagating through them. The dependence of the force on the separation of the slabs is calculated by means of the Maxwell–Stress tensor formalism and its main features are discussed for the different modes of the radiation. Spatially symmetric (antisymmetric) modes give rise to an attractive (repulsiv...

Explicit analysis of anisotropic planar waveguides by the analytical transfer-matrix method.

The propagation properties of light in anisotropic optical planar waveguides with different index distributions are investigated with the analytical transfer-matrix method. Dispersion equations are analytically deduced by the method in terms of different index profiles. It is shown by examples that this method exhibits good accuracy compared with numerical methods while still holding physical i...

Spatiotemporal coupling in dispersive nonlinear planar waveguides

The multidimensional nonlinear Schrödinger equation governs the spatial and temporal evolution of an optical field inside a nonlinear dispersive medium. Although spatial (diffractive) and temporal (dispersive) effects can be studied independently in a linear medium, they become mutually coupled in a nonlinear medium. We present the results of numerical simulations showing this spatiotemporal co...

Spatial optical solitons in planar glass waveguides

We report experimental studies of spatial optical solitons in a nonlinear glass waveguide. Spatial solitons are self-trapped beams that propagate without diffraction. We demonstrate the formation of spatial solitons, and we investigate interactions between them. At high intensities two-photon absorption is observed to lead to the breakup of solitons. A beam propagation method is used to simulat...
