Third-order antibunching from an imperfect single-photon source

February 4, 2014
Author(s)
Martin J. Stevens, Scott C. Glancy, Sae Woo Nam, Richard P. Mirin
We measure second- and third-order temporal coherences, g (2)(τ) and g (3)(τ1, τ2), of an optically excited single-photon source: an InGaAs quantum dot in a microcavity pedestal. Increasing the optical excitation power leads to an increase in the measured

Photon statistics, measurements, and measurements tools

Author(s)
Martin J. Stevens
Single-photon generation and detection is at the forefront of modern optical physics research. This book is intended to provide a comprehensive overview of the current status of single- photon techniques and research methods in the spectral region from the

Multiexciton dynamics in infrared-emitting colloidal nanostructures probed by a superconducting nanowire single-photon detector

Richard L. Sandberg, Lazaro A. Padilha, Mumtaz Qazilbash, Wan Ki Bae, Richard D. Schaller, Jeffrey M. Pietryga, Martin Stevens, Burm Baek, Sae Woo Nam, Victor I. Klimov
Carrier multiplication (CM) is the process in which absorption of a single photon produces multiple electron-hole pairs. Here, we evaluate the effect of particle shape on CM efficiency by conducting a comparative study of spherical nanocrystal quantum dots

Higher-order photon correlations in pulsed photonic crystal nanolasers

December 16, 2011
Author(s)
D. Elvira, X. Hachair, Varun Verma, R. Braive, G. Beaudoin, I. Robert-Philip, I. Sagnes, Burm Baek, Sae Woo Nam, E Dauler, I. Abram, Martin Stevens, A. Beveratos
We report on the higher-order photon correlations of a high-Β nanolaser under pulsed excitation at room temperature. Using a multiplexed four-element superconducting single-photon detector we measured g (n)(0) with n = 2,3,4. All orders of correlation

Generation and characterization of high-purity, pulsed squeezed light at telecom wavelengths from pp-KTP

November 15, 2011
Author(s)
Thomas Gerrits, Martin J. Stevens, Burm Baek, Brice R. Calkins, Adriana E. Lita, Scott C. Glancy, Emanuel H. Knill, Sae Woo Nam, Richard P. Mirin, Robert Hadfield, Ryan Bennink, Warren Grice, Sander N. Dorenbos, Tony Zijlstra, Teun Klapwijk, Val Zwiller
We characterize a pp-KTP crystal designed to produce pure single mode squeezed vacuum at 1570 nm. Measurements show a raw (corrected) Hong-Ou-Mandel interference with 86 % (90 %) visibility and a circular joint spectral probability distribution with a

Time-resolved photoluminescence of lithographically defined quantum dots fabricated by electron beam lithography and wet chemical etching

Author(s)
Varun B. Verma, Martin J. Stevens, Kevin L. Silverman, Neville Dias, Akash Garg, James J. Coleman, Richard P. Mirin
We measure the time-resolved photoluminescence characteristics of a novel type of lithographically patterned quantum dot fabricated by electron beam lithography, wet chemical etching, and overgrowth of the barrier layers by metalorganic chemical vapor

Observing the average trajectories of single photons in a two-slit interferometer

June 3, 2011
Author(s)
Sacha Kocsis, Boris Braverman, Sylvain Ravets, Martin Stevens, Richard Mirin, L. Krister Shalm, Aephraim M. Steinberg
A consequence of the quantum mechanical uncertainty principle is that one may not discuss the path or "trajectory" that a quantum particle takes, because any measurement of position irrevocably disturbs the momentum, and vice versa. Using weak measurements

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

Characterization of high-purity, pulsed squeezed light at telecom wavelengths from pp-KTP for quantum information applications

Thomas Gerrits, Burm Baek, Martin J. Stevens, Brice R. Calkins, Adriana E. Lita, Scott C. Glancy, Emanuel H. Knill, Sae Woo Nam, Richard P. Mirin, Robert Hadfield, Ryan Bennink, Warren Grice, Sander N. Dorenbos, Tony Zijlstra, Teun Klapwijk, Val Zwiller
We characterize a pp-KTP crystal designed to produce pure single mode squeezed vacuum at 1570 nm. Measurements show Hong-Ou-Mandel interference with 97% visibility and a circular joint spectral distribution with a Schmidt number of 1.08.

Superconducting nanowire single-photon detectors

Karl Berggren, Vikas Anant, Burm Baek, E Dauler, X Hu, Andrew J. Kerman, F Marsili, Richard Mirin, Richard J. Molnar, Sae Woo Nam, F Najafi, Martin Stevens, F Wong, Tian Zhong
Existing Superconducting Nanowire Single-Photon Detector (SNSPD) technology achieves simultaneously high device detection efficiency (as high as 57% at 1550 nm optical wavelength [1]), ultrashort jitter performance (30 ps), and a fast reset time ( 3 ns)

Third-order antibunching from an imperfect single-photon source

May 1, 2011
Author(s)
Martin J. Stevens, Scott C. Glancy, Sae Woo Nam, Richard P. Mirin
We measure second- and third-order coherences of an imperfect single-photon source. The magnitude of third-order antibunching indicates that imperfect second-order antibunching results from background emission with Poissonian photon number statistics.
