  • Patent number: 9470855
    Abstract: A multi-chip module (MCM) is described. This MCM includes two substrates that are passively self-assembled on another substrate using hydrophilic and hydrophobic materials on facing surfaces of the substrates and liquid surface tension as the restoring force. In particular, regions with a hydrophilic material on the two substrates overlap regions with the hydrophilic material on the other substrate. These regions on the other substrate may be surrounded by a region with a hydrophobic material. In addition, spacers on a surface of at least one of the two substrates may align optical waveguides disposed on the two substrates, so that the optical waveguides are coplanar. This fabrication technique may allow low-loss hybrid optical sources to be fabricated by edge coupling the two substrates. For example, a first of the two substrates may be a III/V compound semiconductor and a second of the two substrates may be a silicon-on-insulator photonic chip.

  • Patent number: 9022671
    Abstract: A fiber optic connector fiber stub remover and method for automated fiber stub removal. The device has a top plate with a platen opening, and a platen with a well that carries a polishing film over the well. An air pocket is formed between the polishing film and the well. The platen is positioned with a top surface of the polishing film accessible via the platen opening. A fixture holds connector ends of fiber optic cables with fiber stubs extending therefrom, and a weight biases the fiber stubs into contact with the polishing film. A motor is controlled by a motor control unit to control a ramp up time and final speed of movement of the platen over a timespan. Each connector ends moves independently relative to the polishing film. The air pocket provides shock absorption of the polishing film so that an ideal pressure is exerted on each fiber stub during stub removal.

  • Patent number: 8351754
    Abstract: A technique for storing cable slack in an automatic and safe manner, to allow a plug and play connectivity for fiber optic cable installation between floors in multi-floor high-rise apartment buildings. A tamper-proof storage box is located in a prescribed location for which its footprint is intended, such as a utility closet in a lobby or basement. The box contains a number of reels of cable (bundles of individual optical strands), each reel's contents designated for a different floor in the building. As pre-connectorized strands are pulled from a rotatable spindle mounted in the storage box to its intended floor, any cable excess (slack) remains automatically on the spindle in the storage box in an out-of-the-way location avoiding tampering and tripping. This allows off the shelf lengths of cable saving time and expense.
