Polarization dependent dephasing measurements are performed in inhomogeneously broadened Cd x Zn 1-x Te/ZnTe multiple quantum wells at low and high exciton densities. At low temperature and density the self-diffracted signal when the beams are cross-

In this review we detail the dynamics of intrinsic excitons in the alloy Cd x Zn 1- x Te/ZnTe quantum well system. We measure the spectral diffusion of excitons within the inhomogeneously broadened line by time-resolved luminescence. We observe non-r

We review the exciton properties of (Cd, Zn)Te based quantum well structures with the emphasis on LO phonon-exciton interactions. At low temperatures LO phonon emission is an important energy relaxation mechanism for excitons. Low spectral diffusion

A series of Cd 0.33 Zn 0.67 Te/ZnTe single quantum wells of thickness 40 A, 70 A and 100 A are studied using CW and time-resolved photoluminescence techniques. The exciton-photon interaction is found to decrease with decreasing well thickness, this r

We present a fully programmable micro diffraction (F-PMDG) grating in which each micromirror in a 1D array can be individually deflected out-of-plane by up to 1 µm. The maximum operating voltage is 10kHz. The 120 µm wide and 700 µm long mirrors ar

In this paper we detail the dynamics of intrinsic excitons in the alloy Cd x Zn 1− x Te⧸ZnTe quantum well system. Both single and multiple quantum well structures are studied. The strength of the thermal broadening of the exciton is measured up t

Exciton luminescence is studied in a series of Cd 0.33 Zn 0.67 Te/ZnTe single quantum wells as a function of temperature. We find that the broadening of the exciton line with temperature is consistent with LO-phonon scattering. The homogeneous linewi

The technique of resonant Rayleigh scattering is used to determine the homogeneous linewidth across the inhomogeneously broadened exciton resonance in a Cd 0.25 Zn 0.75 Te/ZnTe multiple quantum well structure. An order of magnitude increase of the Ra
