Patent number: 7076146Abstract: A method of controllably attenuating a beam of light coupled into a port includes directing the beam of light against a mirror, and controlling an orientation of the mirror such that a predetermined fraction of the beam of light is coupled into the port. The predetermined fraction is less than a maximum fraction corresponding to optimal coupling of the beam of light into the port. The method may be implemented with a variable optical attenuator including a first port, a second port, a mirror located to direct light output by the first port to the second port, and a controller coupled to the mirror to align it such that the predetermined fraction of light is coupled into the second port. The method may also be implemented with an optical switch.Type: GrantFiled: May 7, 2004Date of Patent: July 11, 2006Assignee: Intel CorporationInventors: Zbigniew Sufleta, Janusz Bryzek, Alex Harwit, James Higgins Smith, Cheng-Chung Huang, Dmitry Vasily Bakin, Steven Saeed Nasiri

Patent number: 6980712Abstract: Methods of calibrating and operating optical switches as well as optical switches in which the orientations of mirrors are measured and controlled using control light beams and position sensing detectors are described. The present invention may provide high resolution control of a plurality of mirrors in an optical switch and thus allow the optical switch to cross-connect a large number of input and output ports with a low insertion loss.Type: GrantFiled: August 26, 2004Date of Patent: December 27, 2005Assignee: Intel CorporationInventors: Cheng-Chung Huang, Steven Saeed Nasiri, Randall Brian Sprague, Alex Harwit, Dmitry Vasily Bakin, Janusz Bryzek

Patent number: 6922500Abstract: An optical fiber switch in accordance with an embodiment of the present invention includes a first plurality of ports, a second plurality of ports, a first plurality of mirrors disposed on a first surface, and a second plurality of mirrors disposed on a second surface. Each one of the first plurality of mirrors is individually controllable to direct light output from a corresponding one of the first plurality of ports to any one of the second plurality of mirrors. Each one of the second plurality of mirrors is individually controllable to direct to a corresponding one of the second plurality of ports light incident on it from any one of the first plurality of mirrors. Advantageously, optical fiber switches in accordance with embodiments of the present invention may couple more than a thousand input ports to more than a thousand output ports with an insertion loss of less than about 3 decibels.Type: GrantFiled: October 24, 2001Date of Patent: July 26, 2005Assignee: Intel CorporationInventors: Cheng-Chung Huang, Steven Saeed Nasiri, Randall Brian Sprague, Alex Harwit, Dmitry Vasily Bakin, Janusz Bryzek

Patent number: 6636656Abstract: An optical switching fabric enables an optical signal entering the device on any one of multiple input ports to be directed to any one of multiple output ports. The present optical switching fabrics include sensing and monitoring devices that permit precise initial calibration and continuous switch connection status monitoring and control. Light entering the switching fabric on an input port is reflected by one of a first set of individually controllable mirrors to one of a second set of individually controllable mirrors and then to a corresponding output port. The switching fabrics include control lasers and position sensing devices which provide output signals corresponding to the orientations of the mirrors. In addition, a subset of the input ports and output ports can be attached to monitor light sources and detectors for recalibration and control.Type: GrantFiled: October 24, 2001Date of Patent: October 21, 2003Assignee: Transparent Networks, Inc.Inventors: Cheng-Chung Huang, Steven S.
