Summary:An optical antenna includes a waveguide structure having a waveguide core and a waveguide fin intersecting substantially under a right angle. A height of the waveguide fin is larger than a height of the waveguide core; and the width of the waveguide core is equal to or larger than twice a height of the waveguide core; and the height of the waveguide fin is equal to or larger than twice a width of the waveguide fin. 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. Embodiments relate to an optical phased antenna array comprising a plurality of such optical antennas arranged in an array configuration.
