Optical Crossbar Switch

View page
US Patent:
6792175, Sep 14, 2004
Filed:
Nov 30, 2000
Appl. No.:
09/726640
Inventors:
Martin Feldman - Baton Rouge LA
Ramachandran Vaidyanathan - Baton Rouge LA
Assignee:
Board of Supervisors of Louisiana State University and Agricultural and Mechanical College - Baton Rouge LA
International Classification:
G02B 635
US Classification:
385 17, 385 15, 385 16, 385 11, 359497
Abstract:
A free space all-optical crossbar switches light from a plurality of sources onto a plurality of receivers, in any arbitrary permutation or combination (including one-to-one and many-to-one permutations). The sources and receivers may, for example, be single mode optical fibers. The polarization of the light from each source is controlled by a series of polarization control devices associated with the source so as to obtain desired angular deflections through a series of polarization-dependent angular deflectors in a first deflection unit. A lens may then direct the light from each source towards its desired receiver. An optional second deflection unit containing polarization control devices associated with individual receivers redirects the light so that it is incident normally on the receivers, an advantage if the receivers are single mode optical fibers. Alternative embodiments are described to reduce the number of optical components and to provide uninterrupted high speed data flow.

Configurable Decoder With Applications In Fpgas

US Patent:
20100180098, Jul 15, 2010
Filed:
Aug 20, 2007
Appl. No.:
12/310217
Inventors:
Ramachandran Vaidyanathan - Baton Rouge LA, US
Matthew Jordan - Huntsville AL, US
Assignee:
Board of Supervisors of Louisana State University and Agricultural and Mechanical College - New Orleans LA
International Classification:
G06F 12/10
US Classification:
711206, 711202, 711E12059
Abstract:
The invention relates to hardware decoders that efficiently expand a small number of input bits to a large number of output bits, while providing considerable flexibility in selecting the output instances. One main area of application of the invention is in pin-limited environments, such as field programmable gates array (FPGA) used with dynamic reconfiguration. The invention includes a mapping unit that is a circuit, possibly in combination with a reconfigurable memory device. The circuit has as input a z-bit source word having a value at each bit position and it outputs an n-bit output word, where n>z, where the value of each bit position of the n-bit output word is based upon the value of a pre-selected hardwired one of the bit positions in the x-bit word, where the said pre-selected hardwired bit positions is selected by a selector address. The invention may include a second reconfigurable memory device that outputs the z-bit source word, based upon an x-bit source address input to the second memory device, where x

Optical Slab Waveguide For Massive, High-Speed Interconnects

View page
US Patent:
63320509, Dec 18, 2001
Filed:
Apr 5, 2000
Appl. No.:
9/543617
Inventors:
Martin Feldman - Baton Rouge LA
Ramachandran Vaidyanathan - Baton Rouge LA
Assignee:
Board of Supervisors of Louisiana State University and Agricultural and
Mechanical College - Baton Rouge LA
International Classification:
G02B 628
H04J 1402
US Classification:
385 24
Abstract:
Optical slab waveguides are used as high-speed, high-capacity interconnects for parallel or other devices. Optical slab interconnects can connect to many more elements than can conventional electrical or fiber optic buses. A multiplexing scheme called "mode division multiplexing" greatly increases the number of independent channels that a single slab can support. Optical slab waveguides have a potential capacity of over one million independent channels, each channel operating at 1 GHz in a single physical medium, with each channel capable of receiving input from over 1000 ports and sustaining a load of over 1000.
