The synthesis of the transfer function of an integrated spectral Bragg filter using the technique of electro-optical phase-shift keying is reported. The demonstrated time of synthesis is less than 1 mus.
We demonstrate here an integrated optical filter based on lithium niobate, with fast electrically reconfigurable transfer function. The technique is based on phase-shift keying of the reflection Bragg grating in a waveguide. The transfer function can be favourably reconfigured by applying different combinations of electrical voltage to the electrode pairs on both sides of the waveguide. The time of...
. Experimental and theoretical studies of the photovoltaic shift in the position of the diffraction efficiency maximum of holograms recorded in LiNbO3 for the case of optimal electric field multiplexing are described. The experimental data are explained using a model in which the bulk photovoltaic field is excited in a crystal that is electrically connected with a low loading resistance. We suggest...
