Ion implanted optical waveguides in nonlinear optical organic crystal.
We report for the first time to our knowledge optical waveguiding in an organic crystalline waveguide produced by ion implantation. Using H+ ions a refractive index barrier suitable for waveguiding has been realized in the highly nonlinear optical organic crystal 4-N, N-dimethylamino-4'-N'-methyl-stilbazolium tosylate (DAST). The refractive index changes in the waveguiding region as a function ...
متن کاملOptical Filters Utilizing Ion Implanted Bragg Gratings in SOI Waveguides
The refractive index modulation associated with the implantation of oxygen or silicon into waveguides formed in silicon-oninsulator (SOI) has been investigated to determine the feasibility of producing planar, implantation induced Bragg grating optical filters. A two-dimensional coupled mode theory-based simulation suggests that relatively short grating lengths, on the order of a thousand micro...
متن کاملEngineering of metal-clad optical nanocavity to optimize coupling with integrated waveguides.
We propose a cladding engineering method that flexibly modifies the radiation patterns and rates of metal-clad nanoscale optical cavity. Optimally adjusting the cladding symmetry of the metal-clad nanoscale optical cavity modifies the modal symmetry and produces highly directional radiation that leads to 90% coupling efficiency into an integrated waveguide. In addition, the radiation rate of th...
متن کاملRealization and infrared to green upconversion luminescence in Er:YALO3 ion-implanted optical waveguides
Ion implantation in optical materials is increasingly used in fabrication of optical waveguides of micrometric dimensions. Implantation has been proved to form planar and channel waveguides in YAG single crystals [1, 2]. Planar waveguides are obtained by homogeneous irradiation of the crystal surface with He or H ions at a given energy (in the MeV range), while mask technique has to be used to ...
متن کاملElectro-optic and nonlinear optical properties of ion implanted waveguides in organic crystals.
We report on the electro-optic and nonlinear optical properties of waveguides produced by low fluence (Phi = 1.25x10(14) ions/cm(2)) H+ ion implantation in the organic nonlinear optic crystal 4-N,N-dimethylamino-4'-N'-methyl-stilbazolium tosylate (DAST). The profile of the nonlinear optical susceptibility has been determined by measuring the reflected second-harmonic generation efficiency from ...
