Phys. Rev. B 51, 11187–11189 (1995)Exciton dispersion in a structure of N coupled multiple quantum wellsReceived 30 September 1994; published in the issue dated 15 April 1995 We derive analytic expressions for the exciton dispersion in N coupled quantum wells. The Förster-type interaction is taken as a mechanism of interwell coupling. The explicit N dependence is obtained, which shows that for any N the dispersion is continuous in all directions and the isolated quantum-well value is reached in the limit of k∥,qν→0 as is physically expected. © 1995 The American Physical Society URL:
