Tech Track 100

Has 89 global patents protecting its silicon photonics technology, which manipulates light within microchips instead of electronic currents, enabling data communication at higher speeds and lower power. It also develops and manufactures miniaturised sensors for use in areas such as consumer healthcare and industrial automation. Its 165 staff are spread across its offices in California (Pasadena and San Jose), Oxford, Cardiff, Cork, and Helsinki. In July 2019, Rockley secured $52m in series E funding from investors including Morningside Technology Ventures of Boston, bringing total funds raised to $165m.

Founder and chief executive Andrew Rickman OBE, 60, previously founded and ran Bookham Technology, the first company to commercialise silicon photonics. It floated in 2000, at a value of £3.9bn, and was ultimately acquired by telecoms firm Lumentum in 2018 for $1.8bn.
