In an extension of earlier work by Moharam et al.[J. Appl. Phys. 50, 5642 (1979)], we use a
perturbation scheme to obtain a higher-order expression for the steady-state photorefractive …

The photorefractive response to an applied electric field is measured in a photorefractive
quantum well, providing evidence in favor of the nonlinear transport in the device due to the …

A laser beam propagating in a photorefractive crystal generates a refractive-index profile
that deflects the beam to one side. This nonlinear deflection can be balanced by total …

The steady‐state space‐charge field and the response time of a photorefractive material
illuminated with a sinusoidal interference pattern are derived for two models in which both …

The photorefractive transport models that include hot-electron transport nonlinearities in the
photorefractive transport equations introduce a new phase-shift mechanism that explains the …

The nonlinear differential equations describing the response of photorefractive material to a
moving sinusoidal intensity pattern that permits large modulation depth are solved by a …

We present a new model (including both temperature and electron‐hole effects) of two‐
beam coupling in photorefractive semiconductors under an external dc field E 0. This model …

It is shown experimentally that the nonsymmetric behavior of the beam-coupling gain
coefficient of BaTiO_3 crystals with respect to the sense of the c axis is caused by an …

We report here for the first time, two‐beam coupling energy transfer using the Franz–
Keldysh electrorefractive effect in photorefractive semiconductors. A large beam coupling …
