John Prineas was the student supported by this AASERT. In our Progress Reports of July 31, 1998 and June 30, 1999, he described his research on radiatively coupled quantum wells with narrow excitation linewidths 0.6 meV and with periods in the vicinity of half the wavelength of light in the semiconducting material X012n 830 nm2x3.6 115 nm 1-8 John won a Deans Fellowship, so he no longer needed AASERT support for his salary. Soon after he received an unusual invitation to spend several months at Bell Laboratories in the laboratory of Jagdeep Shah AASERT funds were used for his travel and living expenses, making possible this industrial experience and leading to very significant results described in the next section and published in Physical Review Letters. John studied the resonance Rayleigh scattering of disordered periodic semiconductor multiple quantum-well structures experimentally with Jagdeep Shah at Bell Labs. Polaritonic effects were found to dominate the secondary emission dynamics due to the coexistence of several radiant modes with different radiative decay times. They give rise to polarization beating between modes and determine rise and decay times of the resonance Rayleigh scattered signals. These results have been published in Physical Review Letters 9.
