Cavity Optomechanical Magnetometer
S. Forstner, S. Prams, J. Knittel +6
A cavity optomechanical magnetometer is demonstrated where the magnetic field induced expansion of a magnetostrictive material is transduced onto the physical structure of a highly…
Feedback Enhanced Sensitivity in Optomechanics: Surpassing the Parametric Instability Barrier
Glen I. Harris, Ulrik L. Andersen, Joachim Knittel +1
The intracavity power, and hence sensitivity, of optomechanical sensors is commonly limited by parametric instability. Here we characterize the parametric instability induced sensi…
Cavity optoelectromechanical regenerative amplification
Michael A. Taylor, Alex Szorkovszky, Joachim Knittel +3
Cavity optoelectromechanical regenerative amplification is demonstrated. An optical cavity enhances mechanical transduction, allowing sensitive measurement even for heavy oscillato…
Detection limits in plasmonic whispering gallery mode biosensors
Jon D. Swaim, Joachim Knittel, Warwick P. Bowen
We analyze a whispering gallery mode biosensor with a metallic nanorod bound to its surface. It is found that a localized surface plasmon resonance in the nanorod can reduce the op…
