Abstract
An optical module is described, where the optical module installs an optical device whose identification mark is able to be distinguished even after the optical device is installed in the optical module. The identifying mark of the optical device is formed in a position able to be inspected from the direction of the normal line of the light-emitting facet of the optical device. Accordingly, the identifying mark becomes able to be identified through the lens after the optical device is installed in the package of the optical module.
Claims11
An optical device with semiconductor layers on a semiconductor substrate, said semiconductor layers including an active layer that generates light along a direction parallel to said semiconductor layers and a light-emitting facet intersecting said direction,
- 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 said direction.
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.
