ABSTRACT:
Integrated optical network comprising:an array of optical waveguides having respective output ends defining a array of radiating elements, wherein said guides receive respective optical input signals and output said optical signals from said radiating elements to form an optical beam; andactuator means to introduce in said array of guides relative phase differences between said optical signals in order to deflect the optical beam formed;characterized in thatthe actuator means include at least one actuator track comprising a plurality of track sections substantially aligned with respective optical guides, said sections being fed by a common control signal to locally modify refractive indexes of the respective optical guides in order to introduce said phase differences.
