Dual-Wavelength $φ$-OFDR Using a Hybrid-Integrated Laser Stabilized to an Integrated SiN Coil Resonator
Published 31 Oct 2024 in physics.optics | (2411.00237v1)
Abstract: We demonstrate dual-wavelength distributed acoustic sensing over 37 km of standard single-mode fiber using $\phi$-OFDR, utilizing a scalable hybrid-integrated dual-wavelength laser chip frequency-locked to a high-Q integrated SiN coil resonator.
