CAVITY OPTOMECHANICAL SENSORS

June 5, 2011
Author(s)
Houxun H. Miao, Kartik A. Srinivasan, Matthew T. Rakher, Marcelo I. Davanco, Vladimir A. Aksyuk
We report a novel type of fully integrated optomechanical sensor and demonstrate high sensitivity mechanical displacement measurements on chip. We sense the motion of micro and nano-mechanical devices by near field coupling them to high quality factor

Temporal Correlation of Photons Following Frequency Up-conversion

May 23, 2011
Author(s)
Lijun Ma, Matthew T. Rakher, Martin Stevens, Oliver T. Slattery, Kartik Srinivasan, Xiao Tang
We demonstrate an approach to measure temporal correlations of photons in the near infrared range using frequency up-conversion. In this approach, the near infrared signal photons are converted into the visible range, in which highly efficient silicon

An efficient, optical fiber-based waveguide interface to a single quantum dipole

October 12, 2009
Author(s)
Marcelo I. Davanco, Kartik A. Srinivasan
We theoretically investigate a single emitter embedded in a hybrid optical waveguide that proves highly efficient, optical fiber access to the dipole transition. A photoluminescence collection efficiency above 70 \% and an approximately 15 dB transmission

Investigations of a coherently driven semiconductor optical cavity QED system

September 30, 2008
Author(s)
Kartik A. Srinivasan, Christopher P. Michael, Raviv Perahia, Oskar Painter
Chip-based cavity QED devices consisting of a self-assembled InAs quantum dot (QD) coupled to a high quality factor GaAs microdisk cavity are coherently probed through the optical channel using a fiber taper waveguide. We highlight one particularly
