High-resolution spectroscopic measurements of InGaAs/GaAs self-assembled quantum dots

May 12, 2006
Author(s)
Joseph J. Berry, Martin Stevens, Richard Mirin, Kevin L. Silverman
We report development of two absorption-based spectroscopic methods that have been adapted from atomic physics techniques to elucidate the basic physical properties of InGaAs/GaAs self-assembled quantum dots(SAQDs). Absorptive spectroscopic measurements

High-resolution spectral hole burning in InGaAs/GaAs quantum dots

February 10, 2006

Joseph J. Berry, Martin Stevens, Richard Mirin, Kevin L. Silverman
We report the use of continuous wave spectral hole burning to perform high-resolution spectroscopy of the homogeneous linewidth of self-assembled InGaAs/GaAs quantum dots at low temperature. We use this technique to examine the power broadening behavior of

Single photon source characterization with a superconducting single photon detector

December 26, 2005
Author(s)
Robert Hadfield, Martin Stevens, Stephen Gruber, Aaron J. Miller, Robert E. Schwall, Richard Mirin, Sae Woo Nam
Superconducting single photon detectors (SSPD) based on nanopatterned niobium nitride wires offer single photon counting at fast rates, low jitter, and low dark counts, from visible wavelengths well into the infrared. We demonstrate the first use of an

On-demand Single Photons from Individual Epitaxial Quantum Dots

October 24, 2005
Author(s)
Richard P. Mirin, Martin J. Stevens
We will describe our group's efforts to use epitaxial InGaAs/GaAs quantum dots as sources of on-demand single photons and indistinguishable single photons. We have demonstrated second order intensity correlation measurements, g 2τ, with g 2(0) as low as 0
