Abstract
Lowest reported threshold organic semiconductor VCSEL (4.9 μJ/cm<sup>2</sup>) is achieved when excitons coherently couple, upon ultrafast non-resonant optical excitation. Temperature dependence of λ/2n device, absent in >= 1.0λ/n cavities, indicates excitons undergo condensate-like phase transition.
