CST Global Leads Single Photon LED Project


QR_SPLED project to develop technology for next generation quantum key-based network security

UK III-V foundry CST Global, a subsidiary of Sivers IMA Holding AB, is leading a Government-funded project 'GaSb/GaAs Quantum Ring Single Photon LED (QR_SPLED').

QR_SPLED seeks to mass-produce low-cost, single-photon LEDs (SPLEDs); a critical technology step in the development of commercially viable, next generation, intrinsic, network security.

Manus Hayne from the Department of Physics at Lancaster University is the academic partner on the project. He is the recognised world-authority on GaSb/GaAs quantum rings and their use in devices such as telecoms-wavelength, VCSELs.

Thomas Slight (pictured), research engineer at CST Global and project lead, explains: "To successfully produce next generation, secure networks we must first mass-produce low-cost, single-photon, LED sources. They provide two, enabling security elements. The first being that the single photon LED can transmit unique, 'key exchange', encryption and decryption data within each data packet, making it impossible to hack. The second being that any attempt to measure, or "˜eavesdrop', on communications is immediately detected and the communication terminated."

The QR-SPLED project (ref: EP/P034233/1) is UK government funded through Innovate UK and the Engineering and Physical Sciences Research Council (EPSRC), in the framework of the UK National Quantum Technologies Programme, with additional funding expected for developing a packaged, SPLED solution later.

The QR-SPLED project runs from March 2017 until February 2018.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
