Electroholographic switching with a rise time of is henceforth presented. The switching was demonstrated in a potassium lithium tantalate crystal doped with copper and titanium with . The crystal was operated at . The switching operation was done in the configuration, in which the Bragg condition remains fulfilled at all levels of the applied field. As electroholography is a wavelength-selective switching method, this opens the way for implementing optical packet switching and fast wavelength addressing schemes in optical fiber networks that apply wavelength division multiplexing.
