Electric-field-induced coherent coupling of the exciton states in a single quantum dot
The ability to generate entangled photon pairs from a quantum dot critically depends on the size of the fine-structure splitting of its exciton states. A demonstration of the ability to tune this splitting wit...

Quantum dots for single photon and photon pair technology
The excitation of a quantum dot from its ground state depends on the probabilistic nature of carrier capture, and thus radiative decay can occur via a multi photon cascade. It is also possible that non-radiati...

Automated Welding Process Sensing and Control
A welding machine requires three additional basic components for truly automated operation:
Sensors which detect physical properties of the weld such as reinforcement area or f...
