A strongly-coupled organic microcavity light-emitting diode is fabricated using a distributed Bragg reflector as one of the cavity mirrors. The device is characterized with electroluminescence, photoluminescence, and time-resolved measurements, and the efficiency is compared to that of a weakly-coupled device. A theoretical treatment of polariton formation is used to explain the lower efficiency of the polariton device.
