Abstract
Aspects of the present disclosure describe optical phased array structures and devices in which hyperbolic phase envelopes are employed to create focusing and diverging emissions in one and two dimensions. Tuning the phase fronts moves focal point spot in depth and across the array. Grating emitters are also used to emit light upward (out of plane). Adjusting the period of the gratings along the light propagation direction results in focusing the light emitted from the gratings. Changes in the operating wavelengths employed moves the focal spot along the emitters.
