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

June 3, 2021
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
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
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
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
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
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
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
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
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
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

Coalescence of Single Photons Emitted by Disparate Single Photon Sources: The Example of InAs Quantum Dots and Parametric Down-Conversion Sources

October 5, 2011
Sergey V. Polyakov, Andreas Muller, Alexander E. Ling, Natalia B. Rutter, Edward B. Flagg, Edward Van Keuren, Alan L. Migdall, Glenn S. Solomon
In quantum mechanics, particles in identical states are indistinguishable, giving rise to effects with no classical analog. Single photons produced by fundamentally dissimilar physical processes will in general not be indistinguishable. We show how photons

4-bar-quasi-phasematching for second-harmonic generation in microdisks

August 15, 2011
Paulina S. Kuo, Glenn S. Solomon
We present a theoretical description of resonantly enhanced, 4-bar-quasi-phasematched, second-harmonic generation in microdisks made of materials possessing 4-bar symmetry, such as GaAs, GaP and ZnSe. The theory describes the interplay between quasi

Indistinguishability of single photons from dissimilar single-photon sources

June 14, 2011
Sergey V. Polyakov, Glenn S. Solomon, Edward B. Flagg, Alan L. Migdall, Andreas Muller
In quantum mechanics, particles in identical states are indistinguishable, giving rise to effects with no classical analog. For instance, the bosonic nature of light insures that upon interference two indistinguishable photons will coalesce into a single

Resolved sideband emission from dynamically strained quantum dots

July 16, 2010
Michael Metcalfe, Stephen M. Carr, Andreas Muller, Glenn S. Solomon, John R. Lawall
The dynamic response of InAs/GaAs self-assembled quantum dots (QDs) to strain is studied by periodically modulating the QDs with a surface acoustic wave (SAW) and measuring the QD fluorescence with both photoluminescence and resonant spectroscopy. When the

Ultrahigh finesse low mode volume Fabry-Perot microcavity

July 1, 2010
Andreas Muller, Edward B. Flagg, John R. Lawall, Glenn S. Solomon
Ultralow loss concave micromirrors with radii of curvature below 60 um were fabricated by laser ablation and reflective coatings. A 10 um long microcavity with a mode volume of 40 um^3 was set up with two such mirrors and the cavity linewidth measured both

Interference of Single Photons from Two Separate Semiconductor Quantum Dots

April 1, 2010
Edward B. Flagg, Andreas Muller, Sergey V. Polyakov, Alexander E. Ling, Glenn S. Solomon
We demonstrate and characterize interference between discrete photons emitted by two separate semiconductor quantum dot states in different samples excited by a pulsed laser. Their energies are tuned into resonance using strain. The photons have a total

Quasi-phasematched Second Harmonic Generation in GaAs Microdisks

November 15, 2009
Paulina S. Kuo, W Fang, Glenn S. Solomon
We discuss design and tuning of second-harmonic generation in GaAs microdisks. Quasi-phasematching can be achieved in the microdisk geometry without external domain inversions, but efficient nonlinear optical mixing requires that all waves be resonant
