Germanium-based quantum emitters for time-reordering entanglement scheme with degenerate exciton and biexciton states

Nicola Dotti, Francesco Sarti, Sergio Bietti +7

We address the photoluminescence emission of individual germanium extrinsic centers in Al_0.3Ga0.7As epilayers grown on germanium substrates. Through a thorough analysis of micro-p…
