Multiple-time-scale blinking in InAs quantum dot single photon sources

April 16, 2014
Author(s)
Marcelo I. Davanco, C S. Hellberg, Serkan Ates, Antonio Badolato, Kartik A. Srinivasan
We use photon correlation measurements to study blinking in single, epitaxially-grown selfassembled InAs quantum dots situated in circular Bragg grating and microdisk cavities. The normalized second-order correlation function g(2)( t) is studied across

Si3N4 optomechanical crystals in the resolved-sideband regime

January 27, 2014
Author(s)
Marcelo I. Davanco, Serkan Ates, Yuxiang Liu, Kartik A. Srinivasan
We demonstrate sideband-resolved Si3N4 optomechanical crystals supporting 105 quality factor optical modes at 980 nm, coupled to approximately 4 GHz frequency mechanical modes with quality factors of approximately 3000. Optomechanical electromagnetically

Slot-mode-coupled optomechanical crystals

October 22, 2012
Author(s)
Marcelo I. Davanco, Jasper Chan, Amir H. Safavi-Naeini, Oskar Painter, Kartik A. Srinivasan
We design a cavity optomechanical system in which a localized GHz frequency mechanical mode of a nanobeam resonator is evanescently coupled to a high quality factor (Q > 10^6) optical mode of a separate nanobeam optical cavity. Using separate nanobeams

Efficient quantum dot single photon extraction into an optical fiber using a nanophotonic directional coupler

September 19, 2011
Author(s)
Marcelo I. Davanco, Matthew T. Rakher, W. Wegscheider, Dieter Schuh, Antonio Badolato, Kartik A. Srinivasan
We demonstrate a spectrally broadband and efficient technique for collecting photoluminescence from a single InAs quantum dot directly into a standard single mode optical fiber. In this approach, an optical fiber taper waveguide is placed in contact with a
