Continuous-wave organic thin-film distributed feedback laser and electrically driven organic semiconductor laser diode

A method for simulation modeling of an organic laser device having an organic optical gain layer, comprising at least one of (1) to (4) below:

• (1) calculating charge carrier mobility and charge carrier recombination rate in the device to perform electrical simulation;
• (2) solving Helmholtz equation to determine an optical propagation mode in the device to perform optical simulation;
• (3) calculating a temperature distribution in the device caused by heat conduction from a laser beam spot irradiated on the organic optical gain layer to perform temperature simulation and estimate an operation stability;
• and
• (4) calculating a rate equation comprising gain, exciton radiative decay constant kr and exciton non-radiative decay constant knr to estimate laser characteristics.
