Dual-Wavelength φ-OFDR Using a Hybrid-Integrated Laser Stabilized to an Integrated SiN Coil Resonator
Abstract
We demonstrate dual-wavelength distributed acoustic sensing over 37 km of standard single-mode fiber using φ-OFDR, utilizing a scalable hybrid-integrated dual-wavelength laser chip frequency-locked to a high-Q integrated SiN coil resonator.
