Fluoride 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 کاملOptimized Digital Optical Switch Using Proton Exchanged Lithium Niobate Waveguides
The main emphasis in developing DOS has been on achieving low crosstalk (CT). CT in the order of -30 dB is acceptable in conventional DOS and below that value is hard to achieve. Relatively low drive voltage (or power requirements) is also necessary to optimized DOS. This paper depicts the design of Y-branched digital optical switches (DOS) with optimized on-chip area coverage, reduced driving ...
متن کاملSpatial 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 کاملPlanar and UV written channel optical waveguides prepared with siloxane– poly(oxyethylene)–zirconia organic–inorganic hybrids. Structure and optical properties
Organic–inorganic hybrids were prepared using ureapropyltriethoxysilane, methacryloxypropyltrimethoxysilane and acrylic acid modified zirconium(IV) n-propoxide precursors and were characterized by small angle X-ray scattering, X-ray diffraction and photoluminescence spectroscopy. The results indicate an effective interaction between the zirconium-based nanoparticles and the siliceous nanodomain...
متن کاملLithographically fabricated optical antennas with gaps well below 10 nm.
Metal nanostructures that effi ciently capture or radiate electromagnetic waves at optical frequencies offer a means to concentrate electromagnetic energy into deep subwavelength regions. Wessel noted that these structures can therefore be considered antennas. [ 1 ] Recent work has focused on more effi cient designs, termed ‘optical antennas’, which employ small gaps or very sharp tips. [ 2–4 ]...
