Voltage reduction for photorefractive two-wave mixing in InP: Fe by optical gap control

Y Ding, HJ Eichler, B Smandek - Applied Physics A, 1992 - Springer
We report a method to increase the photorefractive two-wave mixing gain coefficient Γ in
semiconductors by using additional incident laser radiation. Two auxiliary beams are used …

All-optical remote switching for multiplexed optical fiber sensors and communications systems

JKA Everard, MA Page-Jones - Journal of lightwave technology, 1995 - ieeexplore.ieee.org

sinusoidal electric field. We demonstrate that the application of an AC field sufficiently …

The Photorefractive Effect

AK Powell, TJ Hall, H Imam, DA Fish - Nonlinear Optics in Signal …, 1993 - Springer
It is remarkable that photorefractive crystals, such as barium titanate, display such enormous
optical nonlinearities with the minimum of optical intensity levels, typically no more than that …

Vectorial coupling in the sillenites under AC-enhancement: low-and high-contrast regimes

O Filippov, K Ringhofer, B Sturman - … Effects, Materials, and Devices, 2003 - opg.optica.org
AC-enhancement of the photorefractive response in the sillenites leads to high values of the
gain factor in the low-contrast region. Analytically and numerically we investigate the …

Applied Nonlinear Optics for Sensor Protection.
