Study of ultrafast Rabi flopping in colloidal quantum dots at room temperature

Abstract

Strong light-matter coupling can be achieved using the optical modes of microcavities and the underlying physics explored using ultrafast spectroscopic techniques. Here, the authors investigate the strong coupling regime between colloidal quantum dots and optical cavities and using femtosecond pump-probe spectroscopy and photoluminescence spectroscopy investigate the role of Rabi flopping.
