Latest Patents
One of his latest patents is for an injection laser package. This innovative design features a hermetically sealed injection laser package that is created by first forming a sub-assembly of a monitoring photodiode on a metal support member and welding it to a heat sink on which the laser is mounted. The heat sink is secured inside the package housing, and a further sub-assembly, comprising a plastics packaged optical fiber hermetically sealed in a fiber support tube, is introduced through an aperture in one wall of the housing. Anchorage means are laser beam welded to this tube and to the heat sink to secure the inner end in position for optimum optical coupling between the laser and the fiber. Another significant patent is for a planar laser mount. This assembly comprises a housing with a front surface extending in a plane parallel to a rear surface. The front surface has a central recess from which a pillar extends for carrying a laser, allowing for optical coupling with the laser by converting the mount assembly to an optical fiber termination.
