  • Chip-scale optomechanical magnetometer
    Patent number: 9897666
    Abstract: An optomechanical oscillator for measuring a magnetic field may include a fixed substrate, a moveable mass separated from the fixed substrate by a slot, a photonic crystal comprising an optomechanical cavity formed at the slot, and a current source operably coupled to provide current to the photonic crystal. The moveable mass may be moveable responsive to placement of the optomechanical oscillator in a magnetic field based on interaction of the magnetic field and the current. The magnetic field may be measureable based on displacement of the moveable mass.
    Type: Grant
    Filed: December 15, 2014
    Date of Patent: February 20, 2018
    Assignee: The Johns Hopkins University
