Publication number: 20180299622Abstract: Hybrid optical integration places very strict manufacturing tolerances and performance requirements upon the multiple elements to exploit passive alignment techniques as well as having additional processing requirements. Alternatively, active alignment and soldering/fixing where feasible is also complex and time consuming with 3, 4, or 6-axis control of each element. However, microelectromechanical (MEMS) systems can sense, control, and activate mechanical processes on the micro scale. Beneficially, therefore the inventors combine silicon MEMS based micro-actuators with silicon CMOS control and drive circuits in order to provide alignment of elements within a silicon optical circuit either with respect to each other or with other optical elements hybridly integrated such as compound semiconductor elements. Such inventive MEMS based circuits may be either maintained as active during deployment or powered off once the alignment has been “locked” through an attachment/retention/latching process.Type: ApplicationFiled: August 17, 2015Publication date: October 18, 2018Inventors: FRANCOIS MENARD, FRÉDERIC NABKI, MICHAËL MÉNARD, MARTIN BÉRARD

Patent number: 10067293Abstract: Unlike most MEMS device configurations which simply switch between two positions in many optical devices the state of a MEMS mirror is important in all transition positions. It may determine the characteristics of an optical delay line system and by that an optical coherence tomography system in one application and in another the number of wavelength channels and the dynamic wavelength switching capabilities in the other. The role of the MEMS is essential and it is responsible for altering the paths of the different wavelengths in either device. It would be beneficial to improve the performance of such MEMS and thereby the performance of the optical components and optical systems they form part of. The inventors have established improvements to the design and implementation of such MEMS mirrors as well as optical waveguide technologies to in-plane optical processing as well as the mid infrared for optical spectroscopy.Type: GrantFiled: March 9, 2015Date of Patent: September 4, 2018Assignee: Transfert Plus, Societe en CommanditeInventors: Michael Menard, Frederic Nabki, Mohamed Rahim, Jonathan Briere, Philippe-Olivier Beaulieu

Patent number: 9917650Abstract: Photonic integration has primarily sought to exploit optical parallelism through wavelength division multiplexing whilst in many instances “brute-force” time division multiplexing offers benefits through reduced complexity and cost. However, photoreceivers are primarily the same now for operation at 10 Gb/s, 20 Gb/s, 40 Gb/s and above as 20 or 25 years ago and exploit the same optical detection—amplification—logic processing design. However, high speed low cost electronics ca be leveraged in conjunction with optical time sampling and logic to provide a new design paradigm. An incoming XGbs?1 optical data stream is sampled and processed by N photodetectors each operating at (X/N)Gbs?1 rather than the current direct XGbs?1 front-end of the prior art. Flexibility for the designer in establishing N within optical layer constraints, electronics capabilities etc.Type: GrantFiled: August 26, 2016Date of Patent: March 13, 2018Assignees: TRANSFERT PLUS, SOCIÉTÉ EN COMMANDITE, THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/ MCGILL UNIVERSITYInventors: Odile Liboiron-Ladouceur, Md.

Patent number: 9790765Abstract: An apparatus for sealing at least one hub bore of a multi-bore fluid hub associated with a wellhead assembly includes a plug body having a plug bore opening on an outer mating surface. A plug bore extends from a first end of the plug body to the plug bore opening. The plug body is selectively insertable into a hub housing of the multi-bore fluid hub. An insert is in engagement with the outer mating surface and is moveable relative to the plug body between an unengaged position, and an engaged position where the insert seals across one of the hub bores. A stem member is coupled to the plug body and is moveable to selectively rotate the plug body within the multi-bore fluid hub so that the plug bore opening aligns with one of the hub bores and the insert aligns with another of the hub bores.Type: GrantFiled: October 6, 2014Date of Patent: October 17, 2017Assignee: GE OIL & GAS PRESSURE CONTROL LPInventors: Lloyd Ray Cheatham, Ben Calvin Holgate, Travis Kyle McEvoy, Christopher Michael Menard, Christopher Joseph Dibernardo

Publication number: 20170293083Abstract: External modulators, variable optical attenuators, optical gates, etc. employing Mach-Zehnder interferometers (MZIs) are a common structure within photonic integrated circuits and solutions for addressing the ever increasing demands for larger bandwidth and higher capacity in telecommunication and datacom networks. In most applications, but particularly data centers with potentially tens of thousands of optical links where direct board level applications would be preferred with CMOS compatibility, low power consumption is required. Equally, reducing the footprint of optical devices whilst increasing the functional integration on a line card for example does little for power consumption unless the device capacitance and drive voltage can be reduced as well. Accordingly, it would be beneficial to provide MZIs that require reduced phase shifts to reduce power consumption as the square of reduced applied voltage.Type: ApplicationFiled: April 10, 2017Publication date: October 12, 2017Inventors: MICHAEL MENARD, FATEMEH SOLTANI, ANDREW KIRK

Publication number: 20170017042Abstract: Wavelength division multiplexing (WDM) has enabled telecommunication service providers to fully exploit the transmission capacity of optical fibers. State of the art systems in long-haul networks now have aggregated capacities of terabits per second. Moreover, by providing multiple independent multi-gigabit channels, WDM technologies offer service providers with a straight forward way to build networks and expand networks to support multiple clients with different requirements. In order to reduce costs, enhance network flexibility, reduce spares, and provide re-configurability many service providers have migrated away from fixed wavelength transmitters, receivers, and transceivers, to wavelength tunable transmitters, receivers, and transceivers as well as wavelength dependent add-drop multiplexer, space switches etc.Type: ApplicationFiled: March 9, 2015Publication date: January 19, 2017Inventors: FRANCOIS MENARD, MICHAEL MENARD, FREDERIC NABKI, MARTIN BERARD
