20-μm-diameter WGM resonators that include a terfluorene emission layer and a 10-nm-thick layer of Al or Ag were investigated. The plasmon-quenching effect on amplified spontaneous emission was effectively suppressed by the resonator structure.

We developed a device parameter to evaluate the magnitude of the energy transfer in organic WGM resonators. ASE easily occurs under the condition that the energy acceptor molecules become unable to accept energy from the energy donor excitons.
