Critical power for self-focusing in bulk media and in hollow waveguides.

چکیده
We determine the threshold power for self-focusing collapse both in a bulk medium and in a hollow-core waveguide for various spatial profiles. We find that the threshold power for collapse in the waveguide is always equal to the lower-bound prediction for a bulk medium.

Self-focusing on bounded domains
The critical nonlinear Schrödinger equation (NLS) on bounded domains models the propagation of cw laser beams in hollow-core fibers. Unlike the NLS on unbounded domains which models propagation in bulk media, the ground-state waveguide solutions are stable and the condition of critical power for singularity formation is generically sharp. © 2001 Elsevier Science B.V.

متن کاملon the Elastic Stability of Sleeve Stiffened Hollow Columns; Focusing on Determination of Optimal Design Curves (TECHNICAL NOTE)
The stability analysis of sleeve stiffened pin-ended slender hollow columns of pipe or box section is performed in the present study. This is accomplished by using energy method, employing three terms in the assumed approximate deflection function. The lengthy and tedious algebraic manipulations involved in solving the relevant eigenvalue problem, necessitates employing the "MATHEMATICA" softwa...
متن کاملHollow-waveguide delivery systems for high-power, industrial CO(2) lasers.
Hollow-sapphire and metal-dielectric-coated hollow-glass waveguides have been used to deliver CO(2) laser power for industrial laser applications. The transmission, bending loss, and output-beam properties of these waveguides are described. The bore sizes of the hollow-sapphire waveguides were 1070 and 790 μm, and the hollow-glass waveguide had a bore of 700 μm. The waveguides ranged in length ...
متن کاملOptical pulse compression based on nonlinear silicon waveguides and chirped Bragg gratings
Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...
متن کاملSelf-localization in arrays of defocusing waveguides.
Power-dependent switching between the interacting modes of nonlinear dual-core (two-waveguide) couplers has attracted a great deal of interest during the past several years (see, for example, Synder et al.1 for a review of various physically important situations). In the theoretical papers2 -4 it has been demonstrated that three-waveguide nonlinear directional couplers offer some distinct advan...
