Optical propagation is strongly influenced b y t he n umber concentration, size distribution, thermodynamic phase, and spatial distribution of particles in atmospheric clouds. These properties have been investigated in the field using an airborne digital holographic instrument. A laboratory facility has also been developed, in which optical propagation is being investigated in steady-state turbulent-cloud conditions.

Interwell carrier transport, important for efficient LED and laser diode operation, was studied in InGaN multiple quantum wells by time-resolved photoluminescence. A strong increase in transport efficiency was achieved in structures in which GaN barriers were replaced with that of InGaN.
