Paper Abstract

A large vertical electric field can be used to linearly change the fine-structure splitting of a single InGaAs/GaAs quantum dot by over 100 μeV. In each single dot an avoided crossing is observed, where the magnitude of the splitting reaches a minimum value. We confirm in experiment that polarization-entangled photon pair emission occurs from quantum dots tuned in this manner.
