Universal Silicon Ring Resonator for Error-Free Transmission Links

Photonics Research, 2023
Abstract We report the design, fabrication, and characterization of a universal silicon p-n junction ring resonator for C band error-free communication links operated up to 50 Gb/s with co-designed optical modulation and detection performance. The universal p-n junction ring device shows co-designed detection responsivity up to 0.84 A/W, and in
