A laser that could ‘reshape the landscape of integrated photonics’
October 26, 2022
A team of researchers led by Qiang Lin, a professor of electrical and computer engineering, has developed the first multi-color integrated Pockelslaserthat emits high-coherence light at telecommunication wavelengths, allows laser-frequency tuning at record speeds, and is the first narrow linewidth laser with fast configurability at the visible band. It will pave the way for new applications of integrated semiconductor lasers in LiDAR (Light Detection and Ranging) remote sensing that is used, for example, in self- driving cars. The technology could also lead to advances in microwave photonics, atomic physics, and AR/VR.
