Abstract:
1. A multibeam deflector comprising: a plurality of optical deflection devices aligned in a first direction on a single substrate, each of the optical deflection devices being provided for each of a plurality of optical beams and including a slab optical waveguide formed by a material having an electro-optic effect so as to deflect the optical beams incident thereon so that the optical beams simultaneously output from the plurality of optical deflection devices travel in parallel direction; and an output optical system configured to simultaneously receive the optical beams output from said optical deflection devices at different positions and change a direction of an optical axis of each of the optical beams output from said output optical system independently, wherein the output optical system includes a plurality of cylindrical lenses, each of the plurality of cylindrical lenses being provided at a subsequent position in a second direction in which the optical beams travel from the optical deflection devices to the cylindrical lenses, the second direction being parallel to optical axes of the optical beams, each of the plurality of the cylindrical lenses being located at a different position in a direction perpendicular to the first and second directions.
