Optical module

An optical module comprising:

• a semiconductor laser having a first surface and a second surface opposite to each other along a thickness direction, for emitting light from the first surface or the second surface, the semiconductor laser including an active layer disproportionately positioned closer to the first surface, the semiconductor laser including a reflector for reflecting the light outgoing from the active layer in a direction along the first surface toward another direction, the active layer and the reflector monolithically integrated in the semiconductor laser;
• a carrier formed from a light transmissive material and having a third surface and a fourth surface opposite to each other along a thickness direction, with the semiconductor laser mounted on the third surface of the carrier such that the light enters the third surface, the carrier having a lens surface integrally formed on the fourth surface;
• a solder or a brazing material which electrically and mechanically connects the semiconductor laser and the carrier;
• and
• a substrate having an optical waveguide and an optical coupler for guiding the light to the optical waveguide, the optical waveguide and the optical coupler integrated in the substrate,
• wherein one of the first surface and the second surface, which faces the third surface, has a first area and a second area, where the first area is electrically and mechanically connected to the carrier without overlapping the second area where the light passes, and
• the carrier has a main body with the third surface and the fourth surface, and a spacer portion integrated on the fourth surface of the main body, the spacer keeping the lens surface from being in contact with the optical coupler.
