There is a strategic need for a concentrated and coherent effort in single-photon detection in the Shortwave Infrared Light (SWIR) region, as detailed specifically as a requirement in the Blackett Review (2016).
The UK has limited current capability in commercial SWIR single-photon detector technology therefor SPEXS will stimulate a UK SWIR single-photon industry, by performing much of the low TRL research necessary to generate start-up companies or by licences to existing large companies, in a manner similar to the UK CMOS SPAD industry as shown by examples such as ST Microelectronics and PhotonForce Ltd.
