Optical phenomena and dynamics in organic microcavity laser

Formalism for the interaction of organic molecules with a microstructure cavity is presented. We study the effect of emission and absorption properties of organic molecules in a micro-structured cavity on lasing condition. The formalism is based on coupled-mode theory and provides analytical expression for steady state operation. This study suggests routes to obtain an ultra-low threshold organic laser that can ultimately pave the way to development of an electro-luminescent solid-state organic laser device.
