چکیده:

We investigate the impact of optical excitation in organic vertical cavity surface emitting laser (OVCSEL) to achieve lasing condition. Our simulation shows that for theoptical excitation case, triplet excitons quench singlet excitons largely when we apply constant input optical pump. Also we show that for wide pulses, we can use low inputpump power, but, lasing time will be delayed. Finally, we can optimise our structure to get lasing threshold for lowinput optical pump. Reaching low threshold lasing under optical injection enables us to get lasing under electrical injection.
