“A Holy Grail of Integrated Photonics”: EPFL Researchers Reveal Tiny-Yet-Powerful Ultrafast Laser on a Chip

Scientists have revealed a downscaled, lab-sized, high-energy ultrafast laser to the size of a matchhead, enabling futuristic technologies.

Scientists claim they can improve the sensitivity of atomic clocks to measure the quantum superposition of time and possibly explain gravity.
