Abstract
This optical coupling device couples a plurality of beams to a single fiber. A plurality of light sources is arranged at predetermined intervals and emits the plurality of beams. A plurality of collimating lens is arranged to face the plurality of light sources and collimates the plurality of beams emitted from the plurality of light sources. A reduction optical system reduces the beam diameter of the plurality of beams collimated by the plurality of collimating lens. A focusing lens focuses the plurality of beams reduced by the reduction optical system on a fiber. A first distance between the light source and the collimating lens arranged so as to correspond to a beam passing through the center of the reduction optical system is different from a second distance between the light source and the collimating lens arranged so as to correspond to a beam passing through the end portion of the reduction optical system.
