Abstract:
1. An optical module, comprising: an optical device with semiconductor layers on a semiconductor substrate, said semiconductor layers including an active layer and a light-emitting facet, said active layer generating light along a direction parallel to said semiconductor layers, said light-emitting facet intersecting said direction; and a CAN package including a stem with a stem block and a cap with a lens, said optical device being mounted on a side surface of said stem block so as to face said light-emitting facet to said lens, wherein said optical device provides an identifying mark that distinguishes said optical device from other optical devices in a position able to be inspected from outside of said CAN package through said lens, said optical device provides a trench on each side of said active layer, said identifying mark being formed outside of at least one of said trenches with respect to said active layer, and said trenches reach said semiconductor substrate.
