Imaging threshold detector using a phase-conjugate resonator in BaTiO₃

Abstract

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 on spatially resolved grating erasure in photorefractive BaTiO₃ and has the capability of high resolution and low cross talk.
