Librational Feedback Cooling
Charles P. Blakemore, Denzal Martin, Alexander Fieguth +4
Librational motion, whereby a rigid body undergoes angular oscillation around a preferred direction, can be observed in optically trapped, silica microspheres. We demonstrate the c…
Robust kHz-linewidth distributed Bragg reflector laser with optoelectronic feedback
Megan Yamoah, Boris Braverman, Edwin Pedrozo-Peñafiel +3
We demonstrate a combination of optical and electronic feedback that significantly narrows the linewidth of distributed Bragg reflector lasers (DBRs). We use optical feedback from…
Electrically Driven, Optically Levitated Microscopic Rotors
Alexander D. Rider, Charles P. Blakemore, Akio Kawasaki +3
We report on the electrically driven rotation of m-radius, optically levitated dielectric microspheres. Electric fields are used to apply torques to a microsphere's permanen…
