Abstract :
In this letter, we propose a new structure of an organic vertical-cavity surface-emitting laser to be excited electrically. The static and dynamic characteristics of the device are analyzed numerically. We show that the structure can reach the lasing threshold under electrical pump at a current density of 30 A/cm2. With electrical pulse injection, the photon density peak rises, and we can apply a current density as high as 100 A/cm2. Also, the results show that a high interval causes a high peak.
