Nonlinear excitonic birefringence in anisotropic semiconductor quantum wells

Research output: Contribution to conferencePaperpeer-review

Abstract

A new method, the time-resolved nonlinear differential polarimetry, was developed to analyze the ultrafast exciton-exciton interactions in uniaxially strained quantum wells. Semiconductor GaAs quantum wells which exhibited dichroism and birefringence in the spectral vicinity of the heavy hole (hh) exciton resonance were used in the study. The strong light pulse was numerically simulated to compute for the induced nonlinear optical polarization. Results that contain only Pauli blocking effects were seen to differ from those containing exciton interaction effects resulting from the Coulomb interaction.
