Imaging threshold detector using a phase-conjugate resonator in BaTiO3

MB Klein, GJ Dunning, GC Valley, RC Lind… - Optics letters, 1986 - opg.optica.org
We have demonstrated an imaging threshold detector using a phase-conjugate resonator to
provide high spatial resolution and signal regeneration near threshold. The device is based …

Light‐induced dark decays of photorefractive gratings and their observation in Bi12SiO20

FP Strohkendl - Journal of applied physics, 1989 - pubs.aip.org
We find that the temporal shape and speed of dark decays of photorefractive gratings
depend on the light intensity used to write the grating. We attribute this to the fact that the …

Photorefractive spatial light modulation by anisotropic self-diffraction in KNbO3 crystals

E Voit, P Günter - Optics letters, 1987 - opg.optica.org
Photoinduced anisotropic self-diffraction in photorefractive KNbO_3 has been studied. It has
been shown that this type of diffraction is ideally suited for spatial light modulation or …

Photorefractive dynamic optical interconnects

S Weiss, M Segev, S Sternklar, B Fischer - Applied optics, 1988 - opg.optica.org
We present and demonstrate a set of dynamic optical interconnects which are based on the
double phase conjugate mirror with photorefractive wave mixing. These devices are …

Incoherent-to-coherent conversion by use of the photorefractive fanning effect

J Zhang, H Wang, S Yoshikado, T Aruga - Optics letters, 1997 - opg.optica.org
A dynamic incoherent-to-coherent converter using the photorefractive fanning effect is
demonstrated in a BaTiO_ 3: Ce crystal, and high-quality positive replicas of the incoherent …

Optical processing using wave mixing in photorefractive crystals

JP Huignard, P Günter - Photorefractive Materials and Their Applications II …, 2008 - Springer
The mechanism of the photorefractive grating recording and erasure in electrooptic crystals
is discussed in detail in TAP61. We will thus restrict this section to the presentation of the …

Incoherent-erasure joint-transform correlator

J Khoury, G Asimellis, C Woods - Optics letters, 1995 - opg.optica.org
We propose a nonlinear joint-transform correlator that is produced from the erasure of a real-
time hologram by the joint-transform spectrum. Our analysis of this incoherent-erasure …

Effects of saturation on the nonlinear incoherent-erasure joint-transform correlator

G Asimellis, J Khoury, C Woods - JOSA A, 1996 - opg.optica.org
A photorefractive nonlinear joint-transform correlator based on the incoherent-to-coherent
conversion is presented and analyzed. The nonlinearity of this incoherent-erasure joint …
