"But it's going to be a while before we have pure digital photonic compute for non-quantum systems. is they solved the data interconnect problem for traditional high-performance (computing)," he said. Luminous Computing announced today that it raised 105M in a Series A round, with participation from investors including Gigafund, Bill Gates, 8090 Partners, Neo, Third Kind Venture Capital, Alumni Ventures Group, Strawberry Creek Ventures, Horsley Bridge, Modern Venture Partners, among others. Peter Barrett, founder of venture capital firm Playground Global, an investor in Ayar Labs and PsiQuantum, believes in the long-term prospects for silicon photonics for speeding up computing, but says it is a long road ahead. GlobalFoundries Head of Computing and Wired Infrastructure Amir Faintuch said collaboration with PsiQuantum, Ayar, and Lightmatter has helped build up a silicon photonics manufacturing platform for others to use. Semiconductor manufacturers are also gearing up to use their silicon chip-making technology for photonics. It is not just the startups pushing this technology forward. Emerging from stealth mode, Luminous is re-imagining the entire machine learning hardware/software stack. Luminous Computing, a startup building an AI supercomputer using silicon photonics backed by Bill Gates, raised a total of $115 million.

Lightmatter, which builds processors using light to speed up AI workloads in the datacenter, raised a total of $113 million and will release its chips later this year and test with customers soon after. PsiQuantum raised about $665 million so far, although the promise of quantum computers changing the world is still years out. Beyond connecting transistor chips, startups using silicon photonics for building quantum computers, supercomputers, and chips for self-driving vehicles are also raising big funds.
