The understanding of the condition of lasing in the electrically-driven organic semiconductors is presently the very important and intriguing scientific issue. In this presentation, we will compare the emission properties arising from oraganic semiconductor devices in the FET structure bewteen a Fabry-Perot cavity resonator and a feedback distribution resonator both in the optical- and electrical- driven mode. We discuss the lasing condition including the gain loss inside the resonators in organic semiconductor lasers.
