Abstract

Optical 2D Fourier transform spectroscopy (2DFTS) provides insight into the many-body interactions in direct gap semiconductors by separating the contributions to the coherent nonlinear optical response. We demonstrate these features of optical 2DFTS by studying the heavy-hole and light-hole excitonic resonances in a gallium arsenide quantum well at low temperature. Varying the polarization of the incident beams exploits selection rules to achieve further separation. Calculations using a full many-body theory agree well with experimental results and unambiguously demonstrate the dominance of many-body physics.

摘要

光学二维傅里叶变换光谱(2DFTS)通过分离对相干非线性光学响应的贡献,深入了解直接带隙半导体中的多体相互作用。我们通过研究低温下砷化镓量子阱中的重空穴和轻空穴激子共振,展示了光学2DFTS的这些特性。改变入射光束的偏振利用选择定则实现进一步分离。使用完整多体理论的计算结果与实验结果吻合良好,明确证明了多体物理的主导地位。
