Coupling an epitaxial quantum dot to a fiber-based external-mirror microcavity

June 3, 2021
Author(s)
Andreas Muller, Edward B. Flagg, Michael Metcalfe, John R. Lawall, Glenn S. Solomon
We report the coupling of individual InAs quantum dots (QDs) to a single mode of an external-mirror optical microcavity. The external mirror is bonded to a fiber and positioned above a semiconductor sample consisting of a QD-containing GaAs layer grown

Heterodyne measurement of resonant elastic scattering from epitaxial quantum dots

June 3, 2021
Author(s)
Michael Metcalfe, Glenn S. Solomon, John Lawall
Resonant elastic scattering from InAs quantum dots (QDs) is studied by heterodyne spectroscopy. We show theoretically that heterodyne spectroscopy of a two-level quantum emitter is not sensitive to the inelastic fluorescence component. In practice, we

High-performance semiconductor quantum dot-single- photon sources

June 3, 2021
Author(s)
Glenn S. Solomon
Single photons are a key, fundamental element of most quantum optical technologies, be it for the development of large-scale quantum communication networks, for quantum simulation, or for connecting quantum memories in a quantum computer. The ideal single

Observation of chiral photocurrent transport in the quantum Hall regime in graphene

May 24, 2021
Author(s)
Glenn S. Solomon, Olivier Gazzano, Bin Cao, Jiuning Hu, David B. Newell, Tobias Huber, Michael Gullans, Mohammad Hafezi, Tobias Grass
Optical excitation provides a powerful tool to investigate non-equilibrium physics in quantum Hall systems. Moreover, the length scale associated with photo-excited charge carries lies between that of local probes and global transport measurements. Here

Effects of resonant-laser excitation on the emission properties in a single quantum dot

March 27, 2018
Author(s)
Sergey Polyakov, Vivien Loo, Edward Flagg, Glenn S. Solomon, Olivier Gazzano, Tobias Huber
While many solid-state emitters can be optically excited non-resonantly, resonant excitation is necessary for many quantum information protocols as it often maximizes the non-classicality of the emitted light. Here, we study the resonance fluorescence in a

Simultaneous, Full Characterization of a Single-Photon State

November 15, 2017
Author(s)
Tim O. Thomay, Sergey Polyakov, Elizabeth A. Goldschmidt, Glenn S. Solomon, Olivier Gazzano, Vivien Loo
As single-photon sources become more mature and are used more often in quantum information, communications, and measurement applications, their characterization becomes more important. Single-photon-like light is often characterized by its brightness, as

Coherent quantum frequency bridge: phase preserving, nearly-noiseless parametric frequency converter

May 3, 2017
Author(s)
Ivan A. Burenkov, Yu-Hsiang Cheng, Tim O. Thomay, Glenn S. Solomon, Alan L. Migdall, Thomas Gerrits, Adriana E. Lita, Sae Woo Nam, Lynden K. Shalm, Sergey V. Polyakov
We characterize an efficient and nearly-noiseless parametric frequency upconverter. The ultra- low noise regime is reached by the wide spectral separation between the input and pump frequencies and the low pump frequency relative to the input photons. The

Statistically background-free, phase-preserving parametric up-conversion with faint light

July 9, 2015
Author(s)
Yu-Hsiang Cheng, Tim O. Thomay, Glenn S. Solomon, Alan L. Migdall, Sergey Polyakov
We demonstrate phase preservation in a frequency up-conversion process at the single-photon level. This phase preservation enables the applications of frequency conversion of entangled photon pairs. Periodically poled lithium niobate waveguides and a 1550

Dynamics of a pulsed single photon source

December 18, 2012
Author(s)
Sergey V. Polyakov, Edward B. Flagg, Tim O. Thomay, Glenn S. Solomon
We propose and demonstrate a method for an independent verification of a degree of single photon purity and coherence applicable for all single-photon emitters used in pulsed mode. Using two-time second-order correlation measurements, we reconstruct the

Dynamics of the non-classical light from a single solid-state quantum emitter

October 18, 2012
Author(s)
Edward B. Flagg, Sergey Polyakov, Tim O. Thomay, Glenn S. Solomon
We measure the dynamics of a non-classical optical field using two-time second-order correlations in conjunction with pulsed excitation. The technique quantifies single-photon purity and coherence during the excitation-relaxation cycle of an emitter, which
