    Integrated Optical Frequency Can Now Be Manufactured at Scale

    Article obtained from Photonics RSS Feed.

    A collaboration between John Bowers from the University of California, Santa Barbara (UCSB) and Tobias J. Kippenberg from École Polytechnique Fédérale de Lausanne (EPFL) has yielded an integrated on-chip semiconductor laser and resonator capable of producing a laser microcomb. The breakthrough builds on and upscales technology to support applications in optical communications, ultrafast lidar, neuromorphic computing, and the calibration of astrophysical spectrometers.

    The collaboration has been ongoing for several years. In the last decade, the Kippenberg group discovered soliton microcombs, which are chip-scale, optical frequency combs that emit mutually coherent laser lines — that is, lines that are in…
