We report the demonstration of low threshold organic lasers whose nanostructured resonators are fabricated by UV nanoimprint lithography. We compare the nanoimprinted resonators with their master stamp nanostructures, and demonstrate lasers based on the conjugated polymer poly(2,5-Bis(2',5'- Bis(2"-ethylhexlyoxy))-p-phenylenevinylene), with thresholds of ∼1 kW/cm2 and below, which brings them into the regime where they can be optically pumped by a pulsed light-emitting diode.
