We report the observation of photon antibunching from a single, self-assembled InGaAs quantum dot (QD) at temperatures up to 135 K. The second-order intensity
Radio Frequency Indentification (RFID) and other automated identification technologies (AIT) are being used by government and industry to replace barcodes and
The National Institute of Standards and Technology NIST is a United States Government Agency that develops metrology for the use and advancement of industry
We discuss a practical implementation of a photon-counting detector calibration using correlated photon pairs produced by parametric down-conversion. In this

Radio frequency (RF) and analog/mixed-signal (AMS) integrated circuits (ICs) are key enabling components for mobile and wireless communications and their
We demonstrate a new method for measuring transverse stress with 11.8 υm spatial resolution in a fiber Bragg grating sensor, without the use of polarization
Display performance under ambient conditions is as important for display characterization as are darkroom measurements. We review ambient-contrast measurements
The robust retrieval track explores methods for improving the consistency of retrieval technology by focusing on poorly performing topics. The retrieval task in
