Abstract:

Lowest reported threshold organic semiconductor VCSEL (4.9 μJ/cm2) 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.
