Abstract: Optical beam steering and focusing systems, devices, and methods that utilize diffractive waveplates are improved to produce high efficiency at large beam deflection angles, particularly around normal incidence, by diffractive waveplate architectures comprising a special combination of liquid crystal polymer diffractive waveplate both layers with internal twisted structure and at a layer with uniform structure.

Abstract: Methods, systems and devices for diffractive waveplate lens and mirror systems allowing electronically pointing and focusing light at different focal planes. The system can be incorporated into a variety of optical schemes for providing electrical control of transmission. In another embodiment, the system comprises diffractive waveplates of different functionality to provide a system for controlling not only focusing but other propagation properties of light including direction, phase profile, and intensity distribution. The diffractive waveplate lens and mirror systems are applicable to optical communication systems.
