Architecture and designs of modulating both amplitude and phase at the same time in spatial light modulation are described. According to one aspect of the present invention, light propagation is controlled in two different directions (e.g., 0 and 45 degrees) to perform both amplitude modulation and phase modulation at the same time in liquid crystals. In one embodiment, a mask is used to form a pattern, where the pattern includes an array of alignment cells or embossed microstructures, a first group of the cells are aligned in the first direction and a second group of the cells are aligned in the second direction. Depending on applications, two cells from the first group and the second group may correspond to a single pixel or two neighboring pixels, resulting in amplitude modulation and phase modulation within the pixel or within an array of pixels.

An optical device (40) includes an electro-optical layer (46), having an effective local index of refraction at any given location within an active area of the electro-optical layer that is determined by a voltage waveform applied across the electro-optical layer at the location. Conductive electrodes (50, 52) are disposed over opposing first and second side of the electro-optical layer. Control circuitry (26) is configured to apply control voltage waveforms between the conductive electrodes so as to generate a phase modulation profile in the electro-optical layer that causes rays of optical radiation that are incident on the device to converge or diverge with a given focal power, while varying an amplitude of the control voltage waveforms for the given focal power responsively to an angle of incidence of the rays that impinge on the device from a direction of interest.
