  • Patent number: 10215624
    Abstract: An integrated optical tap monitor takes the form of a highly-reflective outer coating disposed over the active region of an associated photodetector. The coating is of a material that allows for a majority of the impinging optical signal to be re-directed into an output path, while passing a small portion of the signal into the photodetector's active region for monitoring purposes. The integrated configuration is small enough to be housed within a standard TO can, and additional optical components (filters, attenuators, etc.) may be co-located with the integrated tap monitor. By virtue of incorporating the monitoring function with a reflective surface, the integrated tap monitor may be substituted for a turning mirror at any place along a signal path and provide the benefit of power monitoring while also performing signal re-direction.

  • Patent number: 10209453
    Abstract: A water-cooled package of an optical fiber head comprising a delivery optical fiber (DOF), a front optical end cap (OEC), a rear OEC, a glass ferrule, and a housing operates for delivering the laser light from DOF to free space. The rear OEC is fusion-spiced with a section of DOF with a cladding exposed whereas the section of DOF is enclosed in a bore of the glass ferrule. When the glass ferrule is connected and sealed between the front OEC and the rear OEC, cooling water in the water-cooled package is prevented from immersing the section of DOF to maintain reliability of DOF. It is, therefore, not needed to bond the section of DOF in a bore of the front OEC to be waterproof, minimizing varying stress-induced speckle patterns and ultimately maintaining beam quality of the laser light exiting from DOF to free space.
