Physics World Optics & Photonics Briefing 2022

Physics World Optics & Photonics Briefing 2022

The smartphone displays needed for high-resolution web browsing soak up lots of energy, while advanced AI algorithms require ever-increasing amounts of processing power. But as fast as these obstacles appear, we see start-up companies emerging to address them. In this Physics World Optics & Photonics Briefing, we profile two companies using novel light-based technologies to do just that.

We also look at a company developing a laser-lit chip technology, based on micron-scale waveguides inscribed into glass, that can create highly power-efficient displays for smartphones or laptops. Read about these exciting developments and many more.
