Organic polaritons: Long-distance relationships

It is possible to strongly mix light and matter excitations by embedding organic dyes in a suitably designed optical microcavity, forming states known as microcavity polaritons. These hybrid light matter states are used to demonstrate energy transfer between organic molecules over long distances. The ability to transfer energy over distances comparable to the wavelength of light has the potential to be of both fundamental and applied interest. Organic semiconductors continue to receive significant interest for application in optoelectronic devices from an applied perspective, including light-emitting devices and photovoltaic devices.
