Summary:
This paper proposes an optical beam scanning antenna consisting of switched beam waveguide and leaky waveguide. Azimuth angle is changed by switching propagating direction inside waveguide and elevation scanning is given by sweeping the wavelength of tunable laser from 1500 to 1600 nm. The proposed antenna geometry is described in detail and wide angle beam scanning method in elevation plane is presented by introducing optical switches. A waffled leaky waveguide is designed and fabricated by silicon photonics process and its beam scanning is also demonstrated.
