TRIPLET BIEXCITON TRANSITION UNDER HIGH MAGNETIC FIELD IN (Cd,Mn)Te/CdTe/(Cd,Mg)Te ASYMMETRIC QUANTUM WELLS

Biexciton spin states in a CdMnTe / CdTe / CdMgTe single quantum well have been investigated by means of the time-integrated and the spectrally-resolved four-wave mixing measurements in magnetic fields. Applying magnetic field in a Faraday geometry, the four-wave mixing signal showed a beat like structure at an early delay-time region with a co-circular (σ+,σ+) configuration. The spectrally-resolved four-wave mixing signals indicated an additional transition appeared at 1 meV higher energy side of the exciton resonance. These results were explained well by a magnetic field induced triplet biexciton transition.

Third-order optical nonlinearity around the exciton resonance in (C6H13NH3)2PbI4 was measured using time-integrated and spectrally-resolved four-wave-mixing (FWM) techniques. For excitation below the exciton resonance, biexciton contribution to the FWM signals was observed. The dephasing energy of the biexcitons was estimated to be larger than 10 meV.
