Abstract
Numerical simulation of light reflection from a lambda/2 GaN microcavity wi th Ga0.8Al0.2N/Ga0.5Al0.5N Bragg mirrors grown on the A-surface of Al2O3 re vealed a Rabi-splitting of the order of 50 meV and remarkable optical aniso tropy. In a separate Bragg mirror, the exciton interference results in a 95 % modulation of reflection spectra. These effects originate from the giant exciton oscillator strength in GaN and a pronounced uniaxial strain in the structure. (C) 1999 Elsevier Science S.A. All rights reserved.
