Reflection of light in the region of excitonic resonances has been studied in periodic CdTe/(Cd,Mg)Te heterostructures with quantum wells. There is a huge increase in the optical reflection coefficient in crystals which satisfy the Bragg conditions kd=ir (where к is the wave vector of the light, and d is the period of the structure). © 7995 American Institute of Physics.
