A study was conducted to investigate the effect of optically pumped lasing in a 'super yellow' film cast onto a gate dielectric and gate conducting electrode. It was observed during the study that light-emitting field-effect-transistor (LEFET) architecture with a distributed feedback (DFB) resonator structure nanoimprinted into the gain medium helped to achieve an electrically pumped plastic laser. Nanoimprint lithography was applied to obtain 1D and 2D DFB grating resonator structures in multilayer films. The study showed that the 2D DFB laser provided a lower lasing threshold compare to 1D DFB laser under same conditions. The nanoimprinted 2D DFB laser showed a lasing threshold of 32nJ/pulse and slope efficiency of 1.2%. The 1D grating provided a high degree of chain orientation for the organic semiconducting polymers in the source-drain channel.
