Abstract: An optical device can include an end-fire optical phased array including an optical splitter to split an optical signal into a plurality of channels, an optical phase controller to control a phase of the optical signal transmitted from the optical splitter, and an end-fire optical radiator to radiate the optical signal transmitted from the optical phase controller. A lens can be further positioned on a path of the radiated optical signal to control a vertical divergence angle of the radiated optical signal.

Abstract: The present disclosure relates to a scanner and an electronic apparatus including the scanner. The scanner according to the present disclosure comprises a mirror, a substrate separated from the outside of the mirror, a first and a second mirror support member, a first and a second mirror spring, and a plurality of combs formed on the substrate and to supply a rotational force based on electrostatic force to the mirror, wherein the substrate includes a first edge and a second edge closer to the mirror than the first edge and placed at a lower position than the first edge, and the optical interference angle at the second edge is greater than the optical interference angle at the first edge. Accordingly, it is possible to output light in both directions of a mirror and thereby to perform wide-angle scanning.
