Patent number: 10951264Abstract: Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Such UWB systems through their receivers may operate in the presence of interfering signals and should provide for robust communications. Accordingly, an accurate and sharp filter that operates at low power is required and beneficially one that does not require a highly accurate power heavy clock. Further, many UWB applications require location and/or range finding of other elements and it would therefore be beneficial to provide a UWB based range finding and/or location capability removing the requirement to add additional device complexity and, typically significant, power consumption.Type: GrantFiled: July 23, 2020Date of Patent: March 16, 2021Assignee: Transfert Plus, Societe en CommanditeInventors: Frederic Nabki, Dominic Deslandes, Mohammad Taherzadeh-Sani, Michiel Soer, Rabia Rassil

Patent number: 10879869Abstract: Reference oscillators are ubiquitous in timing applications generally, and in modern wireless communication devices particularly. Microelectromechanical system (MEMS) resonators are of particular interest due to their small size and potential for integration with other MEMS devices and electrical circuits on the same chip. In order to support their use in high volume low cost applications it would be beneficial for MEMS designers to have MEMS resonator designs and manufacturing processes that whilst employing low cost low resolution semiconductor processing yield improved resonator performance thereby reducing the requirements of the oscillator circuitry. It would be further beneficial for the oscillator circuitry to be able to leverage the improved noise performance of differential TIAs without sacrificing power consumption.Type: GrantFiled: November 7, 2018Date of Patent: December 29, 2020Assignees: Socovar, Societe en Commandite, TRansfer Plus, Sciete en CommanditeInventors: Mohannad Elsayad, Frederic Nabki, Anoir Bouchami

Patent number: 10852530Abstract: Optical spectroscopy is a widely used method to identify the chemical composition of materials and the characteristics of optical signals. Silicon based integrated photonics offers a platform for many optical functions through microelectromechanical systems (MEMS) and microoptoelectromechanical systems (MOEMS), silicon waveguides, integrated CMOS electronics and hybrid integration of compound semiconductor elements for optical gain. Accordingly, it would be beneficial to provide advanced optical tools for techniques such as optical spectroscopy and optical tomography exploiting MOEMS to provide swept filters that offer improved performance, increased integration, reduced footprint, reduced power consumption, increased flexibility, reconfigurability, and lower cost. Further, such MOEMS elements can support the provisioning of swept optical sources, swept filters, swept receivers etc. in the planar waveguide domain without free space optics.Type: GrantFiled: December 10, 2018Date of Patent: December 1, 2020Assignee: Transfert Plus, Societe en CommanditeInventors: Michaël Ménard, Fréderic Nabki, Mohannad Elsayed

Publication number: 20200359311Abstract: Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction.Type: ApplicationFiled: July 24, 2020Publication date: November 12, 2020Inventors: FREDERIC NABKI, DOMINIC DESLANDES, ALEXANDRE DESMARAIS, ANHKIET VUONG, ANIS BOUNIF, WANG YU HAO, WILLIAM PHAM

Publication number: 20200358420Abstract: Micro-machined acoustic and ultrasonic transducer (MAUT), particularly piezoelectric MAUT (PMAUT), performance tradeoffs have meant reasonable pixel depth resolution necessitated low quality factor (Q) transducers with power distributed over a large bandwidth yielding modest imaging ranges whilst high-Q transducers providing higher acoustic power output for longer imaging ranges exhibit extended ringing limiting pixel depth information. Accordingly, the inventors have established MAUTs supporting high-Q transducers for long-range high-resolution imaging by integrating electromechanical actuators (dampers) which can be selectively engaged to mechanically damped the MAUT. In several applications PMAUT arrays are required where all transducer elements should have almost identical resonant frequencies. However, prior art fabrication processes have tended to produce PMAUTs with large inter-chip and inter-wafer variances.Type: ApplicationFiled: May 5, 2020Publication date: November 12, 2020Inventors: ALEXANDRE ROBICHAUD, PAUL-VAHE CICEK, DOMINIC DESLANDES, FREDERIC NABKI

Patent number: 10742191Abstract: Micromachined microelectromechanical systems (MEMS) based resonators offer integration with other MEMS devices and electronics. Whilst piezoelectric film bulk acoustic resonators (FBAR) generally exhibit high electromechanical transduction efficiencies and low signal transmission losses they also suffer from low quality factors and limited resonance frequencies. In contrast electrostatic FBARs can yield high quality factors and resonance frequencies but suffer from increased fabrication complexity. lower electromechanical transduction efficiency and significant signal transmission loss. Accordingly, it would be beneficial to overcome these limitations by reducing fabrication complexity via a single metal electrode layer topping the resonator structure and supporting relatively low complexity/low resolution commercial MEMS fabrication processes by removing the fabrication requirement for narrow transduction gaps.Type: GrantFiled: January 16, 2018Date of Patent: August 11, 2020Assignee: MEMS Vision International Inc.Inventors: Mohannad Elsayed, Mourad El-Gamal, Frederic Nabki, Paul-Vahe Cicek

Publication number: 20200219818Abstract: 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: ApplicationFiled: January 13, 2020Publication date: July 9, 2020Inventors: MICHAEL MENARD, FREDERIC NABKI, MOHAMED RAHIM, JONATHAN BRIERE, PHILIPPE-OLIVIER BEAULIEU

Patent number: 10608699Abstract: Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Today's leading edge modulated sinusoidal wave wireless communication standards and systems achieve power efficiencies of 50 nJ/bit employing narrowband signaling schemes and traditional RF transceiver architectures. However, such designs severely limit the achievable energy efficiency, especially at lower data rates such as below 1 Mbps. Further, it is important that peak power consumption is supportable by common battery or energy harvesting technologies and long term power consumption neither leads to limited battery lifetimes or an inability for alternate energy sources to sustain them. Accordingly, it would be beneficial for next generation applications to exploit inventive transceiver structures and communication schemes in order to achieve the sub nJ per bit energy efficiencies required by next generation applications.Type: GrantFiled: May 31, 2016Date of Patent: March 31, 2020Assignee: Transfert Plus Societe en CommanditeInventors: Frederic Nabki, Dominic Deslandes, Mohammad Taherzadeh-Sani, Michiel Soer

Publication number: 20200049894Abstract: Wavelength division multiplexing (WDM) has enabled telecommunication service providers to provide multiple independent multi-gigabit channels on one optical fiber. To meet demands for improved performance, increased integration, reduced footprint, reduced power consumption, increased flexibility, re-configurability, and lower cost monolithic optical circuit technologies and microelectromechanical systems (MEMS) have become increasingly important. However, further integration via microoptoelectromechanical systems (MOEMS) of monolithically integrated optical waveguides upon a MEMS provide further integration opportunities and functionality options. Such MOEMS may include MOEMS mirrors and optical waveguides capable of deflection under electronic control. In contrast to MEMS devices where the MEMS is simply used to switch between two positions the state of MOEMS becomes important in all transition positions.Type: ApplicationFiled: October 21, 2019Publication date: February 13, 2020Inventors: FRANCOIS MENARD, MICHAEL MENARD, FREDERIC NABKI, MARTIN BERARD, JONATHAN BRIERE

Publication number: 20200049892Abstract: 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: October 21, 2019Publication date: February 13, 2020Inventors: FRANCOIS MENARD, FREDERIC NABKI, MICHAEL MENARD, MARTIN BERARD
