Optical module, method for fabricating the same

An optical module including:

• a bench part including a bench having a principal surface with a first area and a second area, a semiconductor optical device disposed on the first area, and a lens disposed on the first area, the first area and the second area being arranged in a direction of a first axis;
• and
• a cap including a base made of silicon, the cap being disposed on the bench part,
• the cap having a cavity containing the semiconductor optical device and the lens therein,
• the cap including a ceiling extending along a first reference plane, a front wall extending from the ceiling along a second reference plane, and a rear wall extending from the ceiling in a direction from the cap to the bench,
• the semiconductor optical device, the lens and the cap being arranged along an optical reference plane, and
• the second reference plane being inclined at an acute angle with respect to the first reference plane.
