GHz on-chip timing crystals with semiconductor photonics pave the way to new optoelectronic physics and applications

Schematic of the experimental setup. Credit: science (2024). DOI: 10.1126/science.adn7087 Researchers have for the first time observed a timing crystal on a small-scale semiconductor chip oscillating at a rate of several billion times per second, revealing extremely high nonlinear dynamics in the GHz range. The results of the experiment, published in scienceestablish a strong link …
