An optical antenna for optical phased antenna arrays.

An optical antenna comprising a waveguide structure comprising a waveguide core and a waveguide fin intersecting substantially under a right angle, wherein: - a height of the waveguide fin (120) is larger than a height of the waveguide core (110); and - the width of the waveguide core (110) is equal to or larger than twice a height of the waveguide core (110); and - the height of the waveguide fin (120) is equal to or larger than twice a width of the waveguide fin (120); and wherein the waveguide fin is off-centered with respect to the waveguide core at an offset, thereby forming an optical antenna configured to leak radiation in a radiation direction. Further example embodiments relate to an optical phased antenna array comprising a plurality of such optical antennas arranged in an array configuration.
