Abstract
- We report amplified spontaneous emission (ASE) in an optically pumped symmetric thin film waveguide based on poly [2-methoxy-5-(2′-ethylhexyloxy)-1, 4-phenylene vinylene] (MEH-PPV) and electric-field modulation of the ASE in the MEH-PPV thin film. The electric-field quenching of the ASE at 620 nm and the spontaneous emission (SE) at 580 nm was observed, which increased with the electric field. The ASE intensity was more effectively quenched than the SE intensity as the field increased. The field dependence of the ASE and the SE intensity can be attributed to field-induced dissociation of photogenerated excitons in the MEH-PPV thin film. [ABSTRACT FROM AUTHOR]
