On-Chip Group-IV Heisenberg-Limited Sagnac Interferometric Gyroscope at Room Temperature

On-Chip Group-IV Heisenberg-Limited Sagnac Interferometric Gyroscope at Room Temperature

A room-temperature strip-guided “manufacturable” Silicon-on-Insulator (SOI)/GeSn integrated-photonics quantum-gyroscope chip operating at 1550 nm is proposed and analysed. We demonstrate how the entangled photons generated in Si Spontaneous Four Wave Mixing (SFWM) can be used to improve the resoluti...
