Laser cooling of a nanomechanical oscillator to the zero-point energy
Liu Qiu, Itay Shomroni, Paul Seidler +1
Optomechanical cavities in the well-resolved-sideband regime are ideally suited for the study of a myriad of quantum phenomena with mechanical systems, including backaction-evading…
Optomechanics with one-dimensional gallium phosphide photonic crystal cavities
Katharina Schneider, Yannick Baumgartner, Simon Hönl +5
Gallium phosphide offers an attractive combination of a high refractive index ( for vacuum wavelengths up to 4 μm) and a wide electronic bandgap (2.26 eV), enabling optical ca…
Two-Tone Optomechanical Instability and Its Fundamental Implications for Backaction-Evading Measurements
Itay Shomroni, Amir Youssefi, Nick Sauerwein +5
While quantum mechanics imposes a fundamental limit on the precision of interferometric measurements of mechanical motion due to measurement backaction, the nonlinear nature of the…
Strong optomechanical coupling in a slotted photonic crystal nanobeam cavity with an ultrahigh quality factor-to-mode volume ratio
Katharina Schneider, Paul Seidler
We describe the design, fabrication, and characterization of a one-dimensional silicon photonic crystal cavity in which a central slot is used to enhance the overlap between highly…
