Paper Abstract

Compact ferrule-top nano-mechanical resonators with all-fiber optical interrogation are demonstrated. The resonators comprise of a suspended multi-layer graphene film supported by a ceramic ferrule with a bore diameter of 125 μm. The mechanical resonance of the graphene film is excited and detected via a single optical fiber cable, and experimental test shows that the resonant frequency and quality factor of the resonators are in the range of 170-520 kHz and 58.4-250, respectively. The integration of graphene resonator with optical fiber transmission and interrogation would allow the development of practical fiber-optic sensors for force, mass and pressure measurements.
