Optical module

An optical module comprising, in a housing:

• an optical waveguide array having one or a plurality of first optical incidence ports, and a plurality of first optical emission ports,
• an optical functional element array having one or a plurality of second optical incidence ports, and/or one or a plurality of second optical emission ports, and
• between the optical waveguide array and the optical functional element array,
• lens optics using one or a plurality of lenses, and
• a mirror,
• wherein the optical waveguide array and the optical functional element array are affixed to the housing directly or via a sub-mount,
• the lens optics condense optical beams emitted from the optical waveguide array onto the optical functional element array, and the mirror is disposed to convert the propagation direction of the optical beams emitted from the optical waveguide array such that the optical beams are incident onto the optical functional element array,
• the mirror includes functionality for finely adjusting the converted propagation direction of the optical beams propagated between the optical waveguide array and the optical functional element array by finely adjusting the angle of the mirror,
• the lens optics and the mirror are disposed such that the optical waveguide array and the optical functional element array are optically coupled by the lens optics and the mirror, and
• the angle of the mirror is fixed in place after the angle of the mirror is adjusted such that the optical waveguide array and the optical functional element array are optically coupled.
