Abstract
An optical device includes an electro-optical layer, having an effective local index of refraction that is determined by a voltage waveform applied across the electro-optical layer at the location. A first array of first excitation electrodes extend along respective, mutually-parallel first axes in a first direction over the active area on a first side of the electro-optical layer. A second array of second excitation electrodes extend along respective, mutually-parallel second axes in a second direction, orthogonal to the first direction, over the active area on a second side of the electro-optical layer, opposite the first side. Control circuitry is coupled to apply respective control voltage waveforms to the excitation electrodes and is configured to concurrently modify the respective control voltage waveforms applied to both the first excitation electrodes and the second excitation electrodes so as to generate a specified phase modulation profile in the electro-optical layer.
