Patent number: 9678401Abstract: In a method of operating a liquid crystal device having a liquid crystal composition with smectic-A properties, a first waveform is applied to optically clear the device so that it is substantially transparent to visible light and a second waveform is applied to disorder the material of the liquid crystal composition to afford a strongly light-scattering state. The first waveform has a higher frequency than the second, waveform, and the method comprises applying a modified waveform to partially clear at least a portion of the device from the light-scattering state.Type: GrantFiled: September 6, 2012Date of Patent: June 13, 2017Assignees: DOW CORNING CORPORATION, CAMBRIDGE ENTERPRISE LIMITEDInventors: William Alden Crossland, Anthony Bernard Davey, John Richard Moore, Daping Chu, Jonathan Paul Hannington, Terry Clapp

Patent number: 9091809Abstract: The present invention provides an apparatus comprising a plurality of planar waveguides and method of making the same. The apparatus includes first, second, and third layers formed above a substrate and adjacent each other. The second layer is formed between the first and third layers of a material and comprises a plurality of organofunctional siloxane-based resin or polymer waveguides. Each waveguide has an input on one edge of the second layer and an output on one edge of the second layer so that the input and output are on different line-of-sight paths. The plurality of waveguides is formed such that intersections of the waveguides occur at approximately right angles and the outputs and inputs located on edges that are opposite one another are offset from each other in a direction that is perpendicular to the direction of the corresponding input or output signal.Type: GrantFiled: June 25, 2014Date of Patent: July 28, 2015Assignees: DOW CORNING CORPORATION, CAMBRIDGE ENTERPRISE LIMITEDInventors: Joseph Beals, Nikolaos Bamiedakis, Terry Clapp, Jon Degroot, Richard Penty, Ian White, Adrian Wonfor

Patent number: 8885994Abstract: The present invention provides a planar waveguide. In one embodiment, the planar waveguide includes first and third layers formed above a substrate and adjacent each other. The first and third layers are formed of a first material having a first index of refraction. The planar waveguide also includes a second layer formed between the first and third layers of a second material having a second index of refraction that is larger than the first index of refraction. The planar waveguide further includes a plurality of organo-functional siloxane based resin or polymer waveguides formed in the second layer. Each organo-functional siloxane based resin or polymer waveguide has an input on one edge of the second layer and an output on one edge of the second layer so that the input and output are on different line-of-sight paths.Type: GrantFiled: November 21, 2008Date of Patent: November 11, 2014Assignees: Dow Corning Corporation, Cambridge Enterprise LimitedInventors: Joseph Beals, Nikolas Bamiedakis, Terry Clapp, Richard Penty, Ian White, Adrian Wonfor, Jon Degroot

Patent number: 6490389Abstract: The fibre fuse effect, also termed self propelled self focusing (SPSF) is a catastrophic damage mechanism resulting from a runaway thermal affect which can melt optical fibres. A method and apparatus for limiting the damage caused by a fibre fuse is provided by utilising a detector external to the fibre for monitoring the condition of the fibre.Type: GrantFiled: April 6, 2000Date of Patent: December 3, 2002Assignee: Nortel Networks LimitedInventors: Richard Goodwin, Terry Clapp, Alan Robinson, Vincent Handerek

Patent number: 6266464Abstract: It is found that the use of a multimode interference (MMI) section to flatten the pass-bands of an arrayed waveguide grating (AWG) multiplexer/demultiplexer or comb filter introduces undesirable non-linear wavelength dispersion into those pass-bands if that MMI section mixes modes of more than two different orders. This dispersion can be substantially compensated by the use of a tandem arrangement of two AWGs with MMIs of differing length chosen to provide complementary dispersions. In the case of a comb filter, an equivalent compensation can be achieved by arranging for the light to make a second passage through the AWG in the reverse direction.Type: GrantFiled: December 23, 1999Date of Patent: July 24, 2001Assignee: Nortel Networks LimitedInventors: Stephen Day, James E Whiteaway, Alan Fielding, Terry Clapp
