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...
متن کاملFluoride Glasses and Planar Optical Waveguides
Fluoride glasses are of great interest for optical applications, as low phonon energy hosts for rare-earth ions. With an increasing need for more compact optical devices that impose higher dopant concentration, research activity has been focused on the fabrication of fluoride glass planar waveguides to produce integrated lasers and optical amplifiers, especially those based on Er3þ-doped glasse...
متن کاملBragg’s grating coupler in planar optical sol-gel waveguides
The aim of our investigation was to develop a technique of producing Bragg’s grating couplers on planar waveguides obtained by means of the sol-gel technique. Introducting a light beam into the waveguide structure is in the case of planar optical systems always an essential technological problem, requiring simple and reproducible solutions without extending the waveguide structure too much. The...
متن کاملAnisotropic four-wave mixing in planar LiNbO(3) optical waveguides.
We report on the generation of an efficient phase-conjugate wave by anisotropic four-wave mixing in planar iron-doped y-cut LiNbO(3) waveguides. The pump waves are orthogonally polarized with respect to the signal and phase-conjugate waves. Reflectivities of the phase-conjugate signal of as much as 65% are reached in the waveguide. Experimental results are compared with numerical solutions of t...
