High efficiency grating couplers for strain tunable GaAs quantum dot based entangled photon sources
The on-chip integration of single photon and entangled photon emitters such as epitaxially grown semiconductor quantum dots into photonic frameworks is a rapidly evolving research field.GaAs quantum dots offer high Upholstered Stool purity and a high degree of entanglement due to, in part, exhibiting very small fine structure splitting along with s
