ABSTRACT:
Systems and methods for steering at least one of two or more optical input beams and forming a combined optical output beam are disclosed. A system has a waveguide, one or more phase controlling devices and one or more beam steering devices. The waveguide is configured to combine the optical input beams. The one or more phase controlling devices are configured to control a phase of at least one of the optical input beams. The system can form a coherently combined optical output beam. The one or more beam steering devices are configured to laterally steer, angularly steer, or laterally and angularly steer at least one of the optical input beams. The waveguide, in conjunction with the one or more beam steering devices, is configured to form the combined optical output beam that is angularly steered, laterally steered, or angularly and laterally steered.
