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

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

May 1, 2011
Author(s)
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.

Photon antibunching from a single lithographically defined InGaAs/GaAs quantum dot

February 28, 2011
Author(s)
Varun B. Verma, Martin J. Stevens, Kevin L. Silverman, Neville Dias, Akash Garg, James J. Coleman, Richard P. Mirin
We demonstrate photon antibunching from a single lithographically defined quantum dot fabricated by electron beam lithography, wet chemical etching, and overgrowth of the barrier layers by metalorganic chemical vapor deposition. Measurement of the second

Intensity Dynamics in a Waveguide Array Laser

Author(s)
Kevin L. Silverman, Mingming M. Feng, Richard P. Mirin, Steven T. Cundiff, Matt Williams, J. Nathan N. Kutz
We consider experimentally and theoretically the optical field dynamics of a five emitter laser array subject to a linearly decreasing injection current. We have achieved experimentally an array that produces a robust oscillatory power output with a nearly

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

Pure optical squeezing in a single mode is highly desirable for quantum information applications such as continuous variable quantum computing and the generation of optical Schrödinger cat states. To generate optical cat states, photons are subtracted from

Generation of optical coherent-state superpositions by number-resolved photon subtraction from the squeezed vacuum

Thomas Gerrits, Scott C. Glancy, Tracy S. Clement, Brice R. Calkins, Adriana E. Lita, Aaron Miller, Aaron J. Miller, Alan L. Migdall, Sae Woo Nam, Richard P. Mirin, Emanuel H. Knill
We have created heralded coherent-state superpositions (CSSs) by subtracting up to three photons from a pulse of squeezed vacuum light. To produce such CSSs at a sufficient rate, we used our high-efficiency photon-number-resolving transition edge sensor to

Superconducting Transition-Edge Sensors for Waveguide Coupled Single Photon Detection

July 25, 2010

Anna E. Fox, Adriana E. Lita, Brice R. Calkins, Kevin L. Silverman, Richard P. Mirin, Sae Woo Nam
We present the design and important preliminary superconducting properties of an evanescently coupled number resolving single photon detector operating near 1550 nm in development for integration into a silicon-on-insulator waveguide based optical system.

Generation of optical Schrodinger cat states by number-resolved squeezed photon subtraction

Thomas Gerrits, Scott C. Glancy, Tracy S. Clement, Brice R. Calkins, Adriana E. Lita, Aaron J. Miller, Alan L. Migdall, Aaron J. Miller, Sae Woo Nam, Richard P. Mirin, Emanuel H. Knill
We have generated and measured an approximation of an optical Schrödinger cat state by photon subtraction from squeezed vacuum. Figure 1 shows the experimental scheme. Photons are probabilistically subtracted from squeezed vacuum and detected with a photon

Dark pulse quantum dot diode laser

June 7, 2010
Author(s)
Mingming M. Feng, Kevin L. Silverman, Richard P. Mirin, Steven T. Cundiff
We describe an operating regime for passively mode-locked quantum dot diode laser where the output consists of a train of dark pulses, i.e., intensity dips on a continuous background. We show that a dark pulse train is a solution to the master equation for

Wavelength bistability and switching in two-section quantum-dot diode lasers

June 1, 2010

Mingming M. Feng, Kevin L. Silverman, Richard P. Mirin, Steven T. Cundiff
We report lasing wavelength bistability with respect to applied bias on the saturable absorbers in two-section mode-locked quantum dot lasers. We show data from three different devices exhibiting wavelength bistability. All lasers display wavelength
