Abstract: Various embodiments set forth optical patterning systems. In some embodiments, an optical patterning system includes multiple liquid crystal (LC) layers and a substrate including circuitry that is connected to each of the LC layers. Each LC layer is independently addressable, via connections to the circuitry in the substrate, to modulate a different degree of freedom (DOF) of light, such as an amplitude, a phase, a distinct polarization component, or an amplitude or a phase of a polarization component of the light. In addition, each LC layer can be configured to operate in a non-resonant mode, in which light passes through the LC layer a single time, or in a resonant mode, in which light bounces back and forth between reflective layers multiple times to enhance the interaction with the LC layer.
