  • Patent number: 7164702
    Abstract: Micro-optical elements (MOEs) are designed and fabricated onto transparent laser driver substrates to collimate or focus the beams from vertical-cavity surface-emitting lasers (VCSELs) in accordance with specific application requirements. One disclosed example teaches the hybrid integration of a top-emitting 850 mm VCSEL array and a transparent sapphire substrate that supports a monolithic MOE with designated optical functionality. A flip-chipping hybridization technique ensures a realistic and reliable process. The VCSEL beams transmit directly through the MOE structure on the transparent sapphire substrate and become well-controlled optical outputs under precise specifications. The optical power loss in such a beam shaping process is minimized compared to configurations based on conventional optical components.

  • Patent number: 6583445
    Abstract: An integrated electronic-optoelectronic module comprising: an ultrathin silicon-on-sapphire composite substrate; at least one electronic device fabricated in the ultrathin silicon; and at least one optoelectronic device bonded to the ultrathin silicon-on-sapphire composite substrate and in electrical communication with the at least one electronic device fabricated in the ultrathin silicon layer. For example, VCSELs and photodetectors are integrated with CMOS electronic circuitry to provide useful modules for electro-optical interconnects for computing and switching systems.

  • Patent number: 5601037
    Abstract: A freestanding table having a worksurface supported on height-adjustable legs, each having a height-adjusting mechanism. These mechanisms are simultaneously driven through a driving element such as an endless chain driven by a driving sprocket disposed adjacent the underside of the worksurface. The driving sprocket is nonrotatably connected to a rotatable hub supported in a recess in the worksurface, which recess also accommodates a foldable crank. The crank when in a folded and stored position is disposed in the recess so as to be substantially flush with the upper surface of the worksurface. The crank is pivotally joined about a first axis to an intermediate link which in turn is pivotally joined about a second axis to a rotatable hub so that the crank can be pivoted upwardly through an angle of about so as to be disposed above the worksurface to permit manual gripping and hence rotation thereof when height adjustment is desired.
