Abstract
A novel one-dimensional beam deflector based on a hollow Bragg reflector waveguide for RGB imaging was proposed and evaluated by modeling. Large steering range over 30° is possible by only 100 nm change in the hollow air-core thickness. Electrostatic actuation enables fast and precise control of the beam-steering with a low operation voltage. An ultra-small divergence angle and super-high resolution are expected for device lengths of a few millimeters thanks to the high coherency of the output beam. The proposed hollow-waveguide type deflector is extremely compact and can be arrayed with high density.
