Cavity optomechanical spring sensing of single molecules
Label-free bio-sensing is a critical functionality underlying a variety of health- and security-related applications. Micro-/nano-photonic devices are well suited for this purpose and have emerged as promising platforms in recent years. Here we propose and demonstrate an approach that utilizes the optical spring effect in a high-Q coherent optomechanical oscillator to dramatically enhance the s...
متن کاملSensing dispersive and dissipative forces by an optomechanical cavity
We experimentally study an optomechanical cavity that is formed between a mechanical resonator, which serves as a movable mirror, and a stationary on-fiber dielectric mirror. A significant change in the behavior of the system is observed when the distance between the fiber’s tip and the mechanical resonator is made smaller than about 1 μm. The combined influence of Casimir force, Coulomb intera...
متن کاملOn-chip cavity optomechanical coupling
*Correspondence: [email protected] Department of Physics, University of Alberta, T6G 2E1 Edmonton, AB, Canada Abstract Background: On-chip cavity optomechanics, in which strong co-localization of light and mechanical motion is engineered, relies on efficient coupling of light both into and out of the on-chip optical resonator. Here we detail our particular style of tapered and dimpled optical ...

متن کاملSynchronization in an optomechanical cavity.
We study self-excited oscillations (SEO) in an on-fiber optomechanical cavity. Synchronization is observed when the optical power that is injected into the cavity is periodically modulated. A theoretical analysis based on the Fokker-Planck equation evaluates the expected phase space distribution (PSD) of the self-oscillating mechanical resonator. A tomography technique is employed for extractin...
