Conditions for Soliton-Like Wave Propagation in Pockels and Photorefractive Media
We study the conditions for soliton-like wave propagation in the Photorefractive (PR) and electro-optic (i.e., Pockels) material, by using Nonlinear Schrodinger (NLS) equation. The complete NLS equation is solved analytically and numerically by transforming it into the phase space. Our results clearly show the existence of both the dark and bright solitary solutions for the PR medium. Interesti...
متن کاملPrecision microcomb design and fabrication for x-ray optics assembly
Silicon microcombs developed at our laboratory for the precision alignment and assembly of large-area foil optics have previously been demonstrated to achieve submicron-level assembly repeatability with submillimeter-thick flat substrates. In this article we report on a double-side deep reactive-ion etch fabrication process using silicon-on-insulator wafers which was developed to improve the mi...
متن کاملModeling of strain-induced Pockels effect in Silicon.
We propose a theoretical model to describe the strain-induced linear electro-optic (Pockels) effect in centro-symmetric crystals. The general formulation is presented and the specific case of the strained silicon is investigated in detail because of its attractive properties for integrated optics. The outcome of this analysis is a linear relation between the second order susceptibility tensor a...
متن کاملLiNbO3 Pockels cell for Q-switch of Er:YAG laser
Generation of a giant pulse of Er:YAG laser is complicated mainly due to the properties of the Er:YAG active medium itself. It is caused by the short lifetime of the Er:YAG crystal upper laser level and a small gain for one pass of the radiation through the active medium. In our case, a specially designed LiNbO3 electrooptic shutter was used for Qswitching of Er:YAG laser. Brewster angles were ...
متن کاملA Miniature Pockels Cell with Novel Electrode Geometry
This paper discusses important elements of the Pockels sensing cell design. A novel electrode geometry is analyzed in order to obtain maximum sensitivity response from Pockels crystals (Bi(12)GeO(20)). This neither transversal nor truly longitudinal geometry, results in electrical field distribution along the sensing beam path that provides high modulation depth. Demonstrated performance level ...
