Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical “hotspot” of a ...
A new method enables calibrating entire waveforms -- graphical shapes showing how electrical signals vary over time -- rather than just parts of waveforms as is current practice. The new method ...
Laser measurement can calibrate a precision microphone as well as traditional techniques, according to the US National Institute of Standards and Technology (NIST). Such calibration is required in ...
