Molecular Strong Coupling and Cavity Finesse
arxiv(2022)
摘要
Molecular strong coupling offers exciting prospects in physics, chemistry and
materials science. Whilst attention has been focused on including realistic
models for the molecular systems involved, the important role played by the
entire mode structure of the optical cavities employed so far has been largely
overlooked. We show that the extent and effectiveness of molecular strong
coupling is critically dependent on cavity finesse. Low finesse cavities can
show strong coupling as judged from the presence of Rabi splitting in
reflectivity measurements, but give photoluminescence signals equivalent to
that of bare molecules outside the cavity. The emission of light is shown to
involve hybridized light-matter polaritonic states only for cavities with high
finesse. By developing an analytical model of cavity photoluminescence in
multimode structures, we clarify the role of finite finesse in polariton
formation. The detailed nature of the modes supported by a cavity and how these
modes interact with the molecular system - whether on resonance or not - will
be as important in developing a coherent framework for molecular strong
coupling as the inclusion of realistic molecular models.
