Abstract

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