Mechanisms of blueshifts in organic polariton condensates

T. Yagafarov, D. Sannikov, et al.

Discover the fascinating origins of blueshifts in organic polariton condensates, as Timur Yagafarov and colleagues explore how various factors like the intracavity optical Kerr-effect and polariton interactions contribute to these effects. This research predicts a step-like increase in emission energy at the condensation threshold, providing new insights into the dynamism of these systems.

Abstract

This report unravels the origins of blueshifts in organic polariton condensates, examining contributions from intracavity optical Kerr-effect, gain-induced frequency-pulling, polariton interactions, and saturation of optical transitions. It concludes that blueshifts arise from the interplay of saturation effects and intermolecular energy migration, predicting the observed step-like increase in emission energy and linear polarization at the condensation threshold.
