On-Fiber Optomechanical Cavity

27 October, 2012

Abstract: A fully on-fiber optomechanical cavity is fabricated by patterning a suspended metallic mirror on the tip of an optical fiber. Optically induced self-excited oscillations of the suspended mirror are experimentally demonstrated. We discuss the feasibility of employing on-fiber optomechanical cavities for sensing applications. A theoretical analysis evaluates the sensitivity of the proposed sensor, which is assumed to operate in the region of self-excited oscillations, and the results are compared with the experimental data. Moreover, the sensitivity that is obtained in the region of self-excited oscillations is theoretically compared with the sensitivity that is achievable when forced oscillations are driven by applying an oscillatory external force.
