Query: Quantum nonlinear optics with polar J-aggregates in microcavities   We show that an ensemble of organic dye molecules with permanent electric
dipole moments embedded in a microcavity can lead to strong optical
nonlinearities at the single photon level. The strong long-range electrostatic
interaction between chromophores due to their permanent dipoles introduces the
desired nonlinearity of the light-matter coupling in the microcavity. We obtain
the absorption spectra of a weak probe field under the influence of strong
exciton-photon coupling with the cavity field. Using realistic parameters, we
demonstrate that a single cavity photon can significantly modify the absorptive
and dispersive response of the medium to a probe photon at a different
frequency. Finally, we show that the system is in the regime of cavity-induced
transparency with a broad transparency window for dye dimers. We illustrate our
findings using pseudoisocyanine chloride (PIC) J-aggregates in
currently-available optical microcavities.
