CHIP-SCALE OPTOMECHANICAL MAGNETOMETER |
| 摘要 |
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. |

1. An optomechanical oscillator for measuring a magnetic field comprising:
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, wherein the moveable mass is moveable responsive to placement of the optomechanical oscillator in a magnetic field based on interaction of the magnetic field and the current, and wherein the magnetic field is measureable based on displacement of the moveable mass. |
