Abstract:
An optical semiconductor element includes: a surface-emitting type semiconductor laser that emits laser light; a photodetecting element formed above the surface-emitting type semiconductor; a first electrode of a first polarity formed on the surface-emitting type semiconductor laser; a second electrode of a second polarity different from the first polarity formed on the photodetecting element; and an additional electrode that covers the first electrode and the second electrode.
