Abstract:
The achievement of large values of the light–matter coupling in
nanoengineered photonic structures can lead to multiple photonic resonances contributing to the final properties of the same hybrid
polariton mode. We develop a general theory describing multi-mode light–matter coupling in systems of reduced dimensionality, and
we explore their phenomenology, validating our theory’s predictions against numerical electromagnetic simulations. On one
hand, we characterize the spectral features linked with the multi-mode nature of the polaritons. On the other hand, we show how the
interference between different photonic resonances can modify the real-space shape of the electromagnetic field associated with each
polariton mode. We argue that the possibility of engineering nanophotonic resonators to maximize multi-mode mixing, and to alter
the polariton modes via applied external fields, could allow for the dynamical real-space tailoring of subwavelength electromagnetic
fields.
