Photonics West 2023

The Moscone Center, San Francisco
United States


Photonics West is the most important annual event featuring the best in photonics research and technology. It gathers together the optics and photonics community to hear and discuss the latest innovations and research advances. Join Photonics West 2023 with us!

Every year over 20,000 people attend to share their experience and hear about the latest research, technology, devices and systems in lasers, biomedical optics, and optoelectronics. VTT is also joining to the event and presenting the latest research innovations in imaging and optical sensing. Registration is now open!

Come and see our demonstrations

VTT is a world-class R&D partner for imaging and optical sensing solutions​. This year, we will be showcasing our latest R&D innovations in:

  • Uncooled nano-thermoelectric bolometers for infrared imaging

  • Hyperspectral imaging

  • Silicon photonics​

  • Infrared detectors and hyperspectral sensing systems

  • Optical devices

  • Quantum photonics
