MBE growth and characterization of a II-VI distributed Bragg reflector and microcavity lattice-matched to MgTe

► Epitaxial distributed Bragg reflector and microcavity lattice matched to MgTe. ► Tuning of the bandgap and refractive index of the (Cd,Zn,Mg)Te layers with constant lattice parameter. ► High quality distributed Bragg reflector with reflectivity above 95%. ► Enhancement of the quantum well photoluminescence in resonance with the cavity mode.
