Researchers Demonstrate Giant Photonic Isolation and Gyration

Researchers demonstrate giant photonic isolation and gyration

Researchers from the Illinois Grainger College of Engineering are the first to demonstrate a simple and tunable method for realizing asymmetric couplings in integrated photonics. Their findings, published in Physical Review Letters and selected as an Editor's Pick, provide insight into topological physics while introducing a new approach for optical non-reciprocity and photonic gyration.

Superconducting Circuits Enable On-Chip Gyration And Non-Reciprocal Microwave Control.

Researchers demonstrate a method for creating on-chip gyrators—devices enabling unidirectional microwave signal propagation—using modulated superconducting circuits and achieving dB isolation through the engineering of pure gyration, a non-reciprocal coupling realised via spatio-temporal modulation, thereby offering a pathway towards scalable non-reciprocal metamaterials applicable across diverse physical implementations and frequency ranges.
