Abstract: An internal laser module may be capable of providing a similar high performance as that provided by traditional internally cooled laser modules, but with improved cost efficiency and manufacturability. In the internally cooled laser module, a laser subassembly, such as a coaxial semiconductor laser, may be mounted on a thermoelectric cooler cooler-base with several other components enclosed in a properly designed case.

Abstract: A coupling apparatus includes a lens disposed between a port, such as a photodetector, and a light source, such as a fiber. The lens is aligned such that light emitted from the light source is focused by the lens onto the port. Between the lens and light source and/or lens and port, a low contrast medium is disposed to reduce reflection that could degrade signal strength.
