  "textContent": "An integrated photonic circulator is described, an application of which may be deployed on a chip-scale light-detection and ranging (LiDAR) device. The photonic circulator includes a micro-ring resonator waveguide, a heating element, first and second bus waveguides, a magneto-optic substrate, a magneto-optic element, a magnetic ring disposed on a photonic substrate, and a silicon substrate. The first and second bus waveguides are coupled to the micro-ring resonator waveguide, and the micro-ring resonator waveguide is affixed onto a first side of the photonic substrate. The magneto-optic element and the magneto-optic substrate are arranged on the micro-ring resonator waveguide, the magnetic ring is affixed to the magneto-optic substrate, the heating element is affixed to the photonic substrate, the photonic substrate is affixed to the silicon substrate, and the magnetic ring is concentric with the micro-ring resonator.",
