Spatial subharmonics in photorefractive crystals

BI Sturman, A Bledowski, J Otten, KH Ringhofer - JOSA B, 1992 - opg.optica.org
We show analytically and numerically that the refractive-index gratings produced by the
photorefractive effect need not be of the same periodicity as the driving light intensity. Even …

Asymmetric transmission through a photorefractive crystal of barium titanate

KR MacDONALD, J Feinberg, ZZ Ming, P Günter - Optics communications, 1984 - Elsevier
We have investigated the feasibility of using a barium titanate crystal as a unidirectional
device. The nonlinear interaction between a beam and its own reflection from the back face …

Phase shifts of photorefractive gratings and phase-conjugate waves

I McMichael, P Yeh - Optics letters, 1987 - opg.optica.org
We present measurements of the two-wave mixing gain as a function of frequency detuning
