| 20100159975 | System and Method for Providing a Trunked Radio and Gateway - A method is provided in one example and includes receiving a first channel release notification from a communication network at a trunked radio network gateway connecting one or more trunked radio networks to the communication network. The method also includes determining whether the first channel release notification was generated in response to an initial seizure or a release of a channel in a trunked radio network of the gateway. The method further includes suppressing transmission of a further channel release notification based on data included in the first channel release notification that indicates an origin of the channel seizure or the release causing the first channel release notification to be generated. In more specific embodiments, the data includes parameter values indicating an originating source for the seizure or the release and a responding source generating the channel release notification. | 06-24-2010 |

| 20090022448 | Optical device including waveguide grating structure - Optical devices including waveguide grating structures are described. In accordance with one embodiment, an optical device is provided comprising a horizontal waveguide grating structure having at least one waveguiding layer and at least one subwavelength periodic grating layer. The optical device further comprises upper and lower cladding layers immediately adjoining respective upper and lower surfaces of the waveguide grating structure and having refractive indices lower than a lowest-index one of the waveguiding layers, incident radiation propagating through one of the upper and lower cladding layers toward the waveguide grating structure. The waveguide grating structure is configured for peak reflection of the incident radiation at a peak reflection frequency. A cumulative thickness of the waveguiding layers is less than one tenth of a free space wavelength of the incident radiation at the peak reflection frequency divided by an average refractive index of the waveguiding layers. | 01-22-2009 |
| 20090034985 | Optical interconnect - An optical interconnect includes a first circuit board having an optical source and an optical receiver; and a second circuit board having data source and an optical modulator optically coupled with the optical source and optical receiver, wherein the optical modulator is configured to encode data from the data source into an optical signal from the optical source. The optical receiver is configured to receive the optical signal from the optical modulator. A method of optical communication includes generating on a first circuit board an optical signal directed at a second circuit board; modulating the optical signal with data at the second circuit board; reflecting the optical signal to the first circuit board; and demodulating the optical signal to receive the data at the first circuit board. | 02-05-2009 |

| 20110150390 | IN-PLANE OPTICAL WAVE GUIDE WITH AREA BASED SPLITTER - An optical interconnect includes a set of splitters. Each splitter includes a source waveguide, a reflection waveguide, an output waveguide, and a partially reflective mirror element with a reflective coating. The source waveguide and the reflection waveguide are optically coupled to the partially reflective element. A photonic signal from the source waveguide is partially reflected off the reflective coating as a reflected signal into the reflection waveguide. The output waveguide is optically coupled to the opposite surface and configured such that a non-reflected portion of the photonic signal propagates into the output waveguide. The reflective coating includes a reflected surface area interfacing with the photonic signal form the source waveguide, and power of the non-reflected portion is a function of the reflective surface area interfacing with source waveguide. | 06-23-2011 |
| 20110164875 | SYSTEMS AND METHOD FOR ROUTING OPTICAL SIGNALS - Systems and a method for routing optical signals are disclosed. One system includes a first large core hollow metal waveguide configured to guide a substantially coherent optical beam. A second large core hollow waveguide is optically coupled to the first waveguide with a coupling device. The coupling device is configured to divide the coherent optical beam into a transmitted beam and a reflected beam. Beam walk-off within the coupling device causes the transmitted beam to be shifted by an offset amount. The second large core hollow metal waveguide is shifted from the first large core hollow metal waveguide by approximately the offset amount to receive the shifted transmitted beam. | 07-07-2011 |
