  • Abstract
    Lowest reported threshold organic semiconductor VCSEL (4.9 muJ/cm2) is achieved when excitons coherently couple, upon sub-picosecond non-resonant optical excitation. Temperature dependence of lambda/2 n device, absent in ges lambda/n cavities, indicates excitons undergo condensate-like phase transition.
