Cascaded emission of single photons from the biexciton in monolayered WSe2

November 10, 2016
Author(s)
Yu-Ming He, Oliver Iff, Nils Lundt, Vasilij Baumann, Marcelo I. Davanco, Kartik Srinivasan, Sven Hofling, Christian Schneider
Monolayers of transition metal dichalcogenide materials emerged as a new material class to study excitonic effects in solid state. They benefit from the enormous coulomb correlations between electrons and holes, as a result of reduced dielectric screening

Sara Abrahamsson, Robert Ilic, Jan Wisniewski, Brian Mehl, Liya Yu, Lei Chen, Marcelo I. Davanco, Laura Oudjedi, Jean Bernard Fiche, Bassam Hajj, Xin Jin, Joan Pulupa, Christine Cho, Mustafa Mir, Mohamed El Beheiry, Xavier Darzacq, Marcelo Nollmann, Maxime Dahan, Carl Wu, Timothee Lionnett, James Alexander Liddle, Cornelia Bargmann
Multifocus microscopy (MFM) allows high-resolution instantaneous three-dimensional (3D) imaging and has been applied to study biological specimens ranging from single molecules inside cell nuclei to entire embryos. In any live microscopy application

Imaging Nanophotonic Modes of Microresonators using a Focused Ion Beam

January 15, 2016
Author(s)
Kevin A. Twedt, Jie J. Zou, Marcelo I. Davanco, Kartik A. Srinivasan, Jabez J. McClelland, Vladimir A. Aksyuk
Optical microresonators have proven powerful in a wide range of applications, including cavity quantum electrodynamics, biosensing, microfludics, and cavity optomechanics. Their performance depends critically on the exact distribution of optical energy

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

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
