CSC involved in UK National Quantum Technologies Programme projects




7 September 2020

The Compound Semiconductor Centre Ltd (CSC) – a joint venture founded in 2015 between Cardiff University and epiwafer foundry and substrate maker IQE plc of Cardiff, Wales, UK – has announced its involvement in two new projects funded by Innovate UK under the UK National Quantum Technologies Programme.

In July, CSC formally initiated a new £1.9m project in collaboration with partners including III-V optoelectronic foundry Compound Semiconductor Technologies Global Ltd (CST Global) of Glasgow, Scotland, UK, Cardiff University, semiconductor and MEMS device maker INEX Microtechnology Ltd of Newcastle -upon-Tyne, UK, National Physical Laboratory (NPL) and the University of Nottingham to develop a compact laser-pumped atomic magnetometer. The novel sensor correlates the interaction between alkali-metal atoms and an external magnetic field to infer minute changes in surface structures. This allows the detection of micro-defects in materials and objects that are not visible or hidden from view under protective coatings. A wide range of applications includes:

  • detection of corrosion under insulation (which costs £4 trillion globally in downtime and repairs);
  • in-line material characterization and quality control across the >£1.5bn steel industry;
  • accurate detection of underground assets to reduce excavation time and cost during repairs and maintenance (such as transmission lines, gas and water pipes).

“The global non-destructive test market is worth £7bn annually, and higher-sensitivity in-line sensor solutions are desperately required to help meet the net-zero greenhouse-gas target by 2050 via reducing fugitive emissions in aging infrastructure, and increasing materials production efficiency,” says CSC project manager Denise Powell.

In August, CSC started work on a new £5.5m project with nine industry and academic partners led by British battery maker AMTE Power. CSC’s focus is on developing high-performance compound semiconductor laser sources for quantum magnetometers, to enable extremely high-sensitivity magnetic field measurements to grade new batteries leaving the factory and reduce the time taken for the ageing process from weeks to days. This new quantum sensing technology will cut the cost of production and provide additional capability in grading the quality of batteries for electric cars and other uses in the electrification revolution. An immediate application is integration in UK efforts to build a Gigafactory for battery production in the next few years, in anticipation of 50% of UK vehicle production being wholly or partially electric by 2030.

“We need radically new methods of battery assembly, testing and screening to enable truly high-volume battery manufacture to meet the demands of electrification of transport,” says CSC project manager Ali Anjomshoaa. “This project is a great example of the application of UK-derived quantum science to address real-world problems and drive the future of the British automotive, transport and energy industries,” he adds.

“These projects are the latest in a portfolio of innovative technologies that are translating quantum science into UK-based manufacturing to address new global opportunities,” says CSC director Wyn Meredith. “It is essential that we continue to focus on exploitation of our word-class research to keep the UK at the forefront of the industries of the future.”

Rockley listed among top 10 British tech companies to watch




10 September 2020

Rockley Photonics of Pasadena, CA, USA (formed in 2013 to develop a versatile, application-specific silicon photonics platform for optical integration in next-generation sensor systems and communications networks) has been listed in The Sunday Times’ ‘10 Tech Ones to Watch’ list for 2020, which identifies promising private British tech companies from a cross-section of industries that are well positioned to grow rapidly.

Rockley was formed in 2013 by a management team that has previously had success with two silicon photonics companies. Founder & CEO Andrew Rickman founded the first firm to commercialize silicon photonics, Bookham Technology (which had an IPO in 2000, became Oclaro in 2009 and is now a part of Lumentum), and later became chairman of Kotura (sold to Mellanox in 2013). Rockley has developed a highly versatile, third-generation silicon photonics platform specifically designed for the optical I/O challenges facing next-generation sensor systems and communications networks.

Rockley’s photonic technology platform was developed with a focus on high-volume manufacture of highly integrated optical/electronic devices for high-performance applications. Exploiting optimized waveguide dimensions, it is said to offer significant benefits over conventional solutions including the production of higher-density optical circuits, the ability to create more complex integration, better manufacturing tolerances, superior power handling, lower loss and higher-efficiency photonic IC interfaces. The firm says that its technology can be adapted to be application specific, while simplifying manufacturing, assembly, test and validation, and optimizing power, size and cost of complex optical systems.

Rockley is now delivering a new class of non-invasive sensor for health-related sensing and monitoring applications. Its technology enables personalized monitoring of a much larger set of physical and chemical biomarkers than those currently available.

Rockley also develops and supplies photonic chipsets for datacoms applications. Integrated photonics eliminate the need for traditional discrete components and deliver lower-cost, highly scalable solutions for data-center connectivity. It increases bandwidth density, delivers lower energy consumption and significantly reduces the issue of heat.

“Our technology is flexible and powerful and drives multiple applications for a wide range of high-growth market sectors, including consumer sensors, healthcare and data communications,” says Rickman.

Rockley has raised $165m from investors including Applied Materials, Morningside Technology Ventures and Ahren Innovation Capital. A total of $300m in equity and NRE (non-recurring engineering) funding has been raised to date to support commercialization of its unique technology platform.
