a CQW diagram. AlGaAs (gray) and GaAs (blue). Ovals indicate IXs composed of electrons (e) and holes (h). Diagram of the interferometric setup is shown on the right. The emission images produced by each of the two arms of the Mach–Zehnder interferometer are shifted with respect to each other in the x–y plane. b Measured interference pattern \({I}_{{\rm{interf}}}(x,y)\). The isolated interference dislocation is marked by a green circle.
