Abstract
In a semiconductor laser module in which light emitted from a packaged semiconductor laser is incident on an optical fiber via a lens, the semiconductor laser, the lens, the optical fiber, and a holding member which holds the optical fiber are disposed in an integrated module structure, and at least one space in the module has a flow path communicating with an ambient air via an adsorbent.
Claims4
A semiconductor laser module comprising:
- a packaged semiconductor laser;
- a lens;
- an optical fiber on which light emitted from the packaged semiconductor laser is incident via the lens;
- and
- a holding member holding the optical fiber, wherein said semiconductor laser, said lens, said optical fiber, and said holding member are disposed in an integrated module structure of the semiconductor laser module, and
- a space provided in said integrated module comprises a flow path communicating with an ambient air via an adsorbent.
