Engineering J-Aggregate Cavity Exciton-Polariton Devices

Scott Bradley

Considerable theoretical and experimental research in the past two decades has been invested in the physics and engineering of microcavity exciton-polariton devices based on inorganic active materials such as GaAs or CdTe quantum wells. While exciton-polariton phenomena have been demonstrated in the linear optical response of microcavities containing organic materials such as J-aggregate thin films, the research community remains largely divided between inorganic and organic research in exciton polaritons despite their shared basis in polariton theory. In this work, we show how to adapt the techniques utilized in inorganic exciton-polariton research to experimental research in J-aggregate-based microcavity exciton-polariton devices, demonstrating the applicability of linear dispersion theory to predicting the linear optical response of J-aggregate microcavity exciton-polariton devices. Finally, the engineering of nonlinear optical devices utilizing the techniques and metrics associated with inorganic microcavity exciton-polariton devices will be discussed.
