Patent number: 9470859Abstract: An optical transceiver module is provided with a delatching mechanism that allows module mounting density to be increased while also providing an ergonomic solution that allows the modules to be easily delatched and extracted from their cages. The delatching mechanism is configured to perform early disengagement of the module housing from the cage by delatching the module housing from the cage after the bail has been rotated to an angle that is less than 90°. Because delatching occurs when the bail has been rotated to a delatching angle that is less than 90°, the modules can be more densely stored with less space between modules that are mounted one above the other than with existing solutions.Type: GrantFiled: February 26, 2015Date of Patent: October 18, 2016Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Chaitanya G. Arekar, David J. K. Meadowcroft

Patent number: 9461352Abstract: A multi-step silicon etching process has been developed to fabricate silicon-based terahertz (THz) waveguide components. This technique provides precise dimensional control across multiple etch depths with batch processing capabilities. Nonlinear and passive components such as mixers and multipliers waveguides, hybrids, OMTs and twists have been fabricated and integrated into a small silicon package. This fabrication technique enables a wafer-stacking architecture to provide ultra-compact multi-pixel receiver front-ends in the THz range.Type: GrantFiled: April 15, 2014Date of Patent: October 4, 2016Assignee: California Institute of TechnologyInventors: Cecile Jung-Kubiak, Theodore Reck, Goutam Chattopadhyay, Jose Vicente Siles Perez, Robert H.
