Optomechanical feedback cooling of a 5 mm-long torsional mode
Dianqiang Su, Yuan Jiang, Pablo Solano +3
We report three orders of magnitude optical cooling of the fundamental torsional mode of a 5 mm-long, 550 nm diameter optical nanofiber. The rotation of the nanofiber couples to th…
Cavity optomechanical bistability with an ultrahigh reflectivity photonic crystal membrane
Feng Zhou, Yiliang Bao, Jason J. Gorman +1
Photonic crystal (PhC) membranes patterned with sub-wavelength periods offer a unique combination of high reflectivity, low mass, and high mechanical quality factor. We demonstrate…
From membrane-in-the-middle to mirror-in-the-middle with a high-reflectivity sub-wavelength grating
Corey Stambaugh, Haitan Xu, Utku Kemiktarak +2
We demonstrate a "membrane in the middle" optomechanical system using a silicon nitride membrane patterned as a subwavelength grating. The grating has a reflectivity of over 99.8%,…
Mode competition and anomalous cooling in a multimode phonon laser
Utku Kemiktarak, Mathieu Durand, Michael Metcalfe +1
We study mode competition in a multimode "phonon laser" comprised of an optical cavity employing a highly reflective membrane as the output coupler. Mechanical gain is provided by…
Mechanically Compliant Grating Reflectors for Optomechanics
Utku Kemiktarak, Michael Metcalfe, Mathieu Durand +1
We demonstrate micromechanical reflectors with a reflectivity as large as 99.4% and a mechanical quality factor Q as large as 7.8*10^5 for optomechanical applications. The reflecto…
