| Abstract: | We have studied the reflectivity from heterostructures with a finite number of equidistant quantum wells. A giant amplification of the reflectance has been observed in the multiple quantum wells satisfying the Bragg condition kd=π, where k is the light wavevector in the exciton resonance region and d is the period of the structure. No difference in the photoluminescence intensity and decay time has been found on the Bragg and "anti-Bragg" (kd=π/2) structures. |
