Linear and nonlinear optical properties of Bragg and off-Bragg periodic quantum well structures

Summary form only given. When quantum wells are grown as periodic structures, the radiative properties of the composite system can be very different from those of a single quantum well. The composite radiative decay can be either enhanced or inhibited by the radiative couplings between all of the wells. In order to study the intrinsic behavior in linear and nonlinear experiments, we grew a series of multiple quantum well structures containing up to 200 85-/spl Aring/ thick In/sub 0.04/Ga/sub 0.96/As quantum wells embedded in GaAs barriers, providing almost ideal realizations of such one-dimensional optical lattices.
