Diagnosis of Pulsed Squeezing in Multiple Temporal Modes

August 26, 2008
Author(s)
Scott C. Glancy, Emanuel H. Knill, Thomas Gerrits, Tracy S. Clement, Martin J. Stevens, Sae Woo Nam, Richard P. Mirin
When one makes squeezed light by downconversion of a pulsed pump laser, many temporal / spectral modes are simultaneously squeezed by different amounts. There is no guarantee that any of these modes matches the pump or the local oscillator used to measure

Hanbury Brown-Twiss interferometry without a beamsplitter

August 19, 2008
Author(s)
Martin J. Stevens, Eric Dauler, Burm Baek, Richard J. Molnar, Scott A. Hamilton, Karl Berggren, Richard P. Mirin, Sae Woo Nam
We demonstrate Hanbury-Brown Twiss interferometry without a beamsplitter, by employing a single-mode optical fiber coupled to a multi-element superconducting nanowire single-photon detector.

Homodyne detection of optical cat states generated by squeezed light photon subtraction

August 19, 2008
Author(s)
Thomas Gerrits, Tracy S. Clement, Scott C. Glancy, Sae Woo Nam, Richard P. Mirin, Emanuel H. Knill
We have experimentally created and measured an optical Schrödinger Cat State. The method relies on single photon subtraction off a squeezed vacuum state and conditioning a homodyne measurement on the detection of that photon.

Improving squeezing purity from a KNbO 3 crystal by temperature tuning

May 4, 2008
Author(s)
Thomas Gerrits, Tracy S. Clement, Scott Glancy, Richard P. Mirin, Sae Woo Nam, Emanuel Knill
We show a method to increase the purity of a squeezed state generated by a femtosecond laser and down-conversion crystal. The method relies on temperature tuning the down- and up-converting crystals, which changes the spatial and spectral output mode of

Designing high electron mobility transistor heterostructures with quantum dots for efficient, number-resolving photon detection

May 1, 2008
Author(s)
Mary A. Rowe, Eric Gansen, M. Greene, Danna Rosenberg, Todd E. Harvey, Mark Su, Robert Hadfield, Sae Woo Nam, Richard P. Mirin
We describe the design of the epitaxial layers for an efficient, photon-number-determining detector that utilizes a layer of self-assembled quantum dots as an optically addressable gate in a field-effect transistor. Our design features a dedicated

Submicrometer photoresponse mapping of nanowire superconducting single-photon detectors

December 13, 2007
Author(s)
Robert Hadfield, Paul A. Dalgarno, John A. O'Connor, Euan Ramsay, Richard Warburton, Eric Gansen, Burm Baek, Martin Stevens, Richard Mirin, Sae Woo Nam
We report on the photoresponse mapping of nanowire superconducting single-photon detectors using a focal spot significantly smaller than the device area (10X10 υ 2). Using a confocal microscope configuration and solid immersion lens, we achieve a spot size

Photon-number-discriminating detection using a quantum-dot, optically gated, field-effect transistor

October 1, 2007
Author(s)
Eric Gansen, Mary A. Rowe, M. Greene, Danna Rosenberg, Todd E. Harvey, Mark Su, Robert Hadfield, Sae Woo Nam, Richard Mirin
Detectors with the capability to directly measure the photon number of a pulse of light 1-3 enable linear optics quantum computing 4, affect the security of quantum communications 5, and can be used to characterize 6-8 and herald 9 non-classical states of

Polarization-dependent optical 2D Fourier transform spectroscopy of semiconductors

September 4, 2007
Author(s)
T Zhang, Irina Kuznetsova, T. Meier, X. Li, Richard Mirin, P. Thomas, Steven T. Cundiff
Optical 2D Fourier transform spectroscopy (2DFTS) provides insight into the many-body interactions in direct gap semiconductors by separating the contributions to the coherent nonlinear optical response. We demonstrate these features of optical 2DFTS by

Operational analysis of a quantum dot, optically gated, field-effect transistor as a single-photon detector

July 1, 2007
Author(s)
Eric Gansen, Mary A. Rowe, Marion Greene, Danna Rosenberg, Todd E. Harvey, Mark Su, Robert Hadfield, Sae Woo Nam, Richard Mirin
We report on the operation of a novel single-photon detector, where a layer of self-assembled quantum dots (QDs) is used as an optically addressable floating gate in a GaAs/Al0.2Ga0.8As Δ}-doped field-effect transistor. Photogenerated holes charge the QDs

Wavelength bistability in two-section mode-locked quantum-dot diode lasers

June 1, 2007
Author(s)
Mingming M. Feng, N. A. Brilliant, Steven T. Cundiff, Richard Mirin, Kevin L. Silverman
We report a two-section mode-locked quantum dot laser with an emission wavelength that is bistable with respect to applied bias on the saturable absorber region. The two stable lasing wavelengths for this device are 1173 nm and 1166 nm with a power
