Patent number: 11496219Abstract: A common method of down converting a received RF signal mixes the received RF signal with a LO signal to create a beat signal. Exemplary embodiments can address multiple simultaneously received RF signals which beat within receiver electronics at frequencies similar to that of the down converted signals. An RF mixer is disclosed using a photonic circuit arranged to impose the RF signal and the LO signal onto separate optical beams. An arrangement provides a beam carrying the RF signal to a first optical input of a balanced photodiode receiver and another beam carrying the RF and LO signals to a second optical input of the balanced photodiode receiver. Any beat products formed between different RF signals will be cancelled out at the electrical output of the balanced photodiode receiver.Type: GrantFiled: January 15, 2020Date of Patent: November 8, 2022Assignee: ELONARDO UK LTDInventors: Ian Flint, Taimur Mirza, Shyqyri Haxha

Publication number: 20220278749Abstract: Improving the signal to noise ratio in an optical link involves either reducing the noise or increasing the RF power coupled into the optical link by lowing the voltage, V?, required to induce a phase change of ? of the optical beam passing through the optical modulator. The present disclosure relates to methods and architectures for increasing the optical power through a link through providing one or more laser sources, additional modulators or photodiode receivers and dividing the optical power through these components so that none are overloaded.Type: ApplicationFiled: August 13, 2020Publication date: September 1, 2022Applicant: Leonardo UK LtdInventor: Ian FLINT

Patent number: 11429007Abstract: A Mach Zehnder modulator operates by phase modulating split optical beams with a modulating signal to create dissimilarities in the optical characteristics between the split beams. When the beams are recombined, the dissimilarities gives rise to intensity modulations that are indicative of the modulating signal. One or both beams are modulated with an RF trimming signal. The trimming signal is applied asymmetrically across the two beams thereby reducing the intensity of the optical carrier frequency in one of the beams more than in the other. By selecting the size of the trimming signal the differences in the optical amplitude of the carrier frequency in the two beams can be nulled.Type: GrantFiled: December 24, 2019Date of Patent: August 30, 2022Assignee: LEONARDO UK LTDInventors: Ian Flint, Taimur Mirza, Shyqyri Hahxa

Publication number: 20220212148Abstract: An apparatus for fabricating a graphene membrane includes a first section having a first fluid chamber for housing a suspension of graphene platelets in a fluid. A second section is positionable adjacent the first section. The second section has a second fluid chamber and a porous support housed in the second fluid chamber for supporting a porous substrate. When the first section is positioned adjacent to the second section and the porous substrate is supported by the porous support, the first fluid chamber and the second fluid chamber are in fluid communication via the porous substrate. The apparatus further includes a pressurizer for creating a pressure differential between the first fluid chamber and the second fluid chamber and thereby forcing the fluid through the porous substrate and into the second fluid chamber and lodging the graphene platelets in the pores of the porous substrate.Type: ApplicationFiled: June 10, 2020Publication date: July 7, 2022Applicant: 2599218 ONTARIO INC.Inventors: IAN FLINT, RAYMOND WILLIAMSON

Patent number: 10897313Abstract: An RF signal to be carried by an optical link is modulated onto two optical beams. The modulators are tuned differently so that the distortion products carried on one beam are relatively larger compared to the fundamental compared with other beam. One of the beams is optically upconverted by the appropriate Brillouin shift frequency and the two beams counter-propagated through an optical waveguide in order to create a Brillouin grating. The grating acts to separate the distortion products from the fundamental so as to provide at an output of the link a signal in which the distortion products are insignificant is not absent.Type: GrantFiled: October 18, 2018Date of Patent: January 19, 2021Assignee: LEONARDO MW LTDInventors: Ian Flint, Mohammed Alom, Shyqyri Haxha
