1. A method for operating a plurality of nanoresonators to control a laser light propagation direction, each of the plurality of nanoresonators being a semiconductor p-i-n heterostructure, the method comprising:
applying voltages to each of the plurality of nanoresonators to cause carriers to be injected into i-regions of the plurality of semiconductor p-i-n heterostructure, to change resonant properties of the plurality of nanoresonators by using the carriers injected into the i-regions, and to cause a phase shift to occur in a laser light passing through the plurality of nanoresonators,
wherein the applying the voltages comprises setting the voltages so that the phase shift in each of the plurality of nanoresonators forms phase gradients in a single plane, and wherein the laser light is deflected in accordance with the phase gradients.
