We present wavelength selective switching with a rise time of 25 ns implemented in a slab waveguide constructed in a KLTN:Cu crystal. The waveguide was fabricated by implantations of alpha particles at 2.1 MeV which produced a 0.5 μm thick cladding

We present experimental evidence indicating that in potassium lithium tantalate niobate at the paraelectric phase, ferroelectric clusters are formed to compensate the space charge induced field created in a photorefractive process. These clusters are

We present experimental evidence indicating the formation of metastable dipolar gratings in potassium lithium tantalate niobate at the paraelectric phase. These dipolar gratings result from the formation of local metastable changes in the Curie-Weiss

A generic wavelength-selective switching method is presented. The method is based on the voltage-controlled photorefractive effect in paraelectric crystals. The switch consists of a crystal at the paraelectric phase in which a space charge grating wa

Electric-field multiplexing (EFM) results from the tuning of the effective wavelength of the light beam inside a photorefractive crystal. This tuning results from the application of an external electric field to the crystal during holographic recordi

A fixing process of photorefractive holograms is reported. The process is based on the formation of an ionic space charge which becomes mobile at the phase transition temperature. A fixed grating was formed in paraelectric potassium lithium niobate t

Electroholography (EH) is a generic concept in optoelectronics, which enables to govern the reconstruction process of volume holograms by an external electric field. EH is based on the use of the voltage controlled photorefractive (PR) effect in crys

We present experimental evidence indicating the formation of dipolar holographic gratings in potassium lithium tantalate niobate at the paraelectric phase slightly above the phase transition. These gratings are formed in the dark, following the writi

We describe a new approach for constructing large-scale artificial neural networks. The novelty of our approach is based on the concept of electroholography (EH), which permits interconnecting of electronic neurons by minute-volume holograms, using t
