Abstract: A highly integrated multi-channel optical module is provided. The optical module includes an optical source device mounted on a substrate by an optical source mount unit, a waveguide mounted on the substrate by a waveguide mount unit, a lens mount unit disposed between the optical source device and the waveguide and mounted on the substrate, and a lens unit fixed to the lens mount unit by an adhesive cured by ultraviolet (UV) parallel light, wherein a light path of the UV parallel light is formed in the lens mount unit by a reflector attached on a side surface of the lens mount unit, and the UV parallel light moves along the light path and cures the adhesive coated on an upper portion of the lens mount unit facing a lower end portion of the lens unit.
