CST Global leads QR, Single Photon LED project for next generation, network security.

03 July 2017

CST Global, a wholly owned subsidiary of Sivers IMA Holding AB and the UK’s leading, independent, III-V opto-electronic, semiconductor foundry is leading the GaSb/GaAs Quantum Ring Single Photon LED (QR_SPLED) project. The QR_SPLED project 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.

Dr Manus Hayne from the Department of Physics at Lancaster University is the academic partner on the project. He is the recognized world-authority on GaSb/GaAs quantum rings and their use in devices such as telecoms-wavelength, Vertical Cavity Surface Emitting Lasers (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. UK funding of £252,649 ensures the critical knowledge and expertise generated by this project will remain in the UK and allow CST Global, and other commercial partners, to be at the forefront of the world’s emerging, next generation, quantum telecommunications driven, network security.

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