Abstract
A method and an electro-optical device are presented for affecting the propagation of input light impinging on the device. The electro-optical device is composed of at least one domain-patterned ferroelectric crystal structure with inverted domains, and an electrodes' arrangement on the surface of the at least one structure connected to a voltage source. When the input light is appropriately directed onto the electro-optical device, and voltage is appropriately applied to the electrodes, this causes at least one of the following effects: deflecting a light component of a predetermined wavelengths contained in the input light from the direction of propagation of the input light so as to direct this light component in a reflection output direction, while allowing the other light components to propagate in the direction of propagation of the input light; changing the phase of the input light in a wavelength-dependent manner; and separately controlling the wavelength-dependent transmission and dispersion for different polarizations of light.
