Actively Tuned and Spatially Trapped Polaritons
R. B. Balili, D. W. Snoke, L. Pfeiffer +1
We report active tuning of the polariton resonance of quantum well excitons in a semiconductor microcavity using applied stress. Starting with the quantum well exciton energy highe…

Long-Distance Diffusion of Excitons in Double Quantum Well Structures
Z. Vörös, R. Balili, D. W. Snoke +2
In this Letter we report on lateral diffusion measurements of excitons at low temperature in double quantum wells of various widths. The structure is designed so that excitons live…
