How do you integrate the advantages of a benchtop laser that fills a room onto a semiconductor chip the size of a fingernail?
A research team co-led by Qiang Lin, a professor of electrical and computer engineering at the University of Rochester, has set new milestones in addressing this challenge, with the first multi-color integrated laser that:
- Emits high-coherence light at telecommunication wavelengths
- Allows laser-frequency tuning at record speeds
- Is the first narrow linewidth laser with fast configurability at the visible band
The project, described in Nature Communications, was co-led by John Bowers, distinguished professor at University of California/Santa Barbara, and Kerry Vahala, professor at the California Institute of Technology. Lin Zhu, professor at Clemson University, also collaborated on the project.
