Test of a model of efficient second-harmonic generation in glass optical fibers.
To test a model recently proposed to account for the observation of efficient second-harmonic generation in glass fibers, we have applied a strong dc electric field to the glass preform from which the fibers were drawn. We find that at most a temporary x(2) is induced, with a lifetime of a few minutes.
متن کاملEfficient one-third harmonic generation in highly Germania-doped fibers enhanced by pump attenuation.
We provide a comprehensive study on one-third harmonic generation (OTHG) in highly Germania-doped fiber (HGDF) by analyzing the phase matching conditions for the step index-profile and optimizing the design parameters. For stimulated OTHG in HGDF, the process can be enhanced by fiber attenuation at the pump wavelength which dynamically compensates the accumulated phase-mismatch along the fiber....
متن کاملZnO nanorods for efficient third harmonic UV generation
ZnO nanorods grown by both high temperature vapour phase transport and low temperature chemical bath deposition are very promising sources for UV third harmonic generation. Material grown by both methods show comparable efficiencies, in both cases an order of magnitude higher than surface third harmonic generation at the quartz-air interface of a bare quartz substrate. This result is in stark c...
متن کاملGalerkin Finite-Element Method for the Analysis of the Second Harmonic Generation in Wagon Wheel Fibers
The nonlinear effects of the second harmonic generation have been investigated for the propagation of light along the axis of fibers of wagon wheel cross sectional shape. Nodal finite element formulation is utilized to obtain discretized Helmholtz equations under appropriate boundary conditions. The hierarchical p-version nodal elements are used for meshing the cross section of wagon wheel fibe...
متن کاملThird-harmonic generation in slow-light chalcogenide glass photonic crystal waveguides.
We demonstrate third-harmonic generation (THG) in a dispersion-engineered slow-light photonic crystal waveguide fabricated in AMTIR-1 chalcogenide glass. Owing to the relatively low loss and low dispersion in the slow-light (c/30) regime, combined with the high nonlinear figure of merit of the material (∼2), we obtain a relatively large conversion efficiency (1.4×10(-8)/W(2)), which is 30× high...
