Experimental characterization of 2D exciton coherence area for MoSe2
Abstract
We propose to carry out a detailed quantitative analysis of coherent feedback modulation of optical reflection and photoluminescence spectra in MoSe2, including the impact of excitation laser focusing parameters relative to the exciton coherence area. This analysis will include both the development of detailed theoretical models and experiments on key types of MoSe2 samples. We will use our existing experimental apparatus to perform measurements with both samples grown by chemical vapor deposition and exfoliated flakes encapsulated in high-quality hexagonal boron nitride. We will provide rigorous interpretations of the data, and assess the implications of our results for future work on cavity nonlinear optics (attojoule photonic switching) experiments leveraging two dimensional excitons in MoSe2.
