An international research activity of state-of-the-art experimental laboratories and theoretical modelling
Organic Polaritonics
Circumventing the challenges of epitaxial growth, polariton condensates are also realised in soft-matter organic microcavities. In collaboration with IBM and the University of Sheffield we are investigating the potential of organic microcavities in sustaining polariton condensation at ambient condition and the application of organic polariton condensates for imprinting polariton lattices, a promising platform for simulators, and as optical amplifiers.

Hybrid Polaritonics
Organic materials exhibit exceptional room temperature light emitting characteristics and enormous exciton oscillator strength, however, their low charge carrier mobility prevent their use in high-performance applications such as electrically pumped lasers. In this context, ultralow threshold polariton lasers, whose operation relies on Bose-Einstein condensation of polaritons – part-light part-matter quasiparticles, are highly advantageous since the requirement for high carrier injection no longer holds. Polariton lasers have been successfully implemented using inorganic materials owing to their excellent electrical properties, however, in most cases their relatively small exciton binding energies limit their operation temperature. Here we explore combining organic and inorganic semiconductors in a hybrid microcavity, and exploit resonant interactions between these materials that could permit to dramatically enhance optical nonlinearities and operation temperature. Our investigations pave the way towards realization of hybrid organic-inorganic microcavities that utilise the organic component for sustaining high temperature polariton condensation and efficient electrical injection through inorganic structure.
