Optical module, manufacturing method of optical module, and optical device

A manufacturing method of an optical module, comprising:

• preparing a first substrate which includes an optical waveguide, and
• a first guide provided on an end surface side in an end of the optical waveguide;
• preparing a second substrate which includes a first groove corresponding to the end surface;
• disposing a resin in the first guide;
• disposing an optical component on the resin;
• and
• jointing the second substrate onto the first substrate by pressing the optical component to the resin side by the first groove, wherein
• the first groove is parallel to and extends in an optical axis direction of the optical waveguide.

An optical device, comprising:

• a first substrate configured to include an optical waveguide, and a first guide provided on an end surface side in an end of the optical waveguide;
• a resin configured to be disposed in the first guide;
• a first optical component configured to be disposed on the resin;
• and a second substrate configured to be jointed onto the first substrate, and
• to include a first groove corresponding to an end surface in a surface of the first substrate, the first groove facing the first guide, wherein
• the first optical component includes
• an optical module configured to be disposed between the resin and the first groove, and
• a second optical component configured to be disposed on a side of the optical module, and to be optically coupled to the end surface through the first optical component, wherein
• the first groove is parallel to and extends in an optical axis direction of the optical waveguide.

An optical module, comprising:

• a first substrate configured to include an optical waveguide, and a first guide provided on an end surface side in an end of the optical waveguide;
• a resin configured to be disposed in the first guide;
• an optical component configured to be disposed on the resin;
• and
• a second substrate configured to be jointed onto the first substrate, and to include a first groove corresponding to an end surface in a surface of the first substrate, the first groove facing the first guide, the optical component being disposed between the resin and the first groove, wherein
• the optical component is a lens, a first face of the lens being coupled to the optical waveguide, a second surface opposite to the first face of the lens being configured to be coupled to an optical fiber.
