Abstract

We demonstrate very low threshold laser oscillation (E_th= 0.78 ±0.5 μJ/cm²) from an organic semiconductor thin film employing 2,5-bis(p-(N-phenyl-N-(m-tolyl)amino)styryl)benzene (BSB-Me) as an active gain medium equipped with a second order distributed feedback resonator. Further, we demonstrate laser oscillation under optical excitation from an organic light emitting device equipped with transparent ITO hole and electron injection electrodes. In addition, we demonstrate injection and transport of high current density over J > 500 A/cm² in an organic light emitting diode using highly thermal conductive substrates and a small electrode under short pulse voltage excitation.
