Soon SPIE Photonics West 2025 will open its doors. The largest annual conference and exhibition in optics and photonics will run from 25 to 30 January at the Moscone Center in San Francisco. The event brings together researchers, innovators, engineers, and business leaders from across the globe for an exciting week of research-sharing, collaboration opportunities, and exchanges. This year, the week will include 4,500-plus technical presentations across over 100 technical conferences, as well as showcasing more than 1,200 companies in four focused exhibitions.

SPIE Photonics West has four major application areas:

• Bios highlights new research in biophotonics, biomedical optics, and imaging for diagnostics and therapeutics;
• Lase focuses on the laser industry and its diverse applications;
• Opto covers optoelectronics, photonic materials, and optical devices; and
• Quantum West features quantum 2.0 technologies from quantum sensing and information systems to quantum enabled materials and devices and quantum biology. Quantum West also includes a Quantum West Business Summit highlighting the innovations that are  moving quantum technologies to market.

The Bios Expo, featuring technologies in biomedical optics and healthcare applications, runs 25-26 January. The AR|VR|MR Expo – which focuses on augmented, virtual, and mixed reality and the vital role that optics and photonics play in hardware and headset development – takes place on 29-29 January. Quantum West Expo, 28-29 January, will showcase the latest quantum-enabled and -enabling technologies. The Photonics West Exhibition, running 28-30 January, encompasses the latest innovations from laser manufacturers and suppliers as well as other novel optics and photonics devices, components, systems, and services.
