A photoinduced change in refractive index has been observed and studied in strained CdTe/CdMnTe quantum-well heterostructures grown on CdZnTe substrates in the (111) orientation. The effect stems from a shift of resonant frequencies and from a change in the oscillator strengths of exciton transitions. It reaches a maximum for exciton transitions between the first electron quantum-well subband and the second hole quantum-well subband. © 1995 American Institute of Physics.
