Abstract
An antenna or antenna array for a steerable light beam, the antenna array comprising a plurality of linear antenna arrays (), each linear antenna array comprising: a plurality of antenna elements (); a waveguide () supporting the antenna elements having a length and a thickness; and a control element (), adjacent to the waveguide, arranged to induce a change in refractive index along at least a part of the length of the waveguide and in at least a part of the thickness of the waveguide, wherein the change in refractive index in the waveguide causes a phase shift in light emitted via each of the plurality of antenna elements.
