Abstract

We show that the amplified spontaneous emission (ASE) in poly[2-methoxy, 5-(2′-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) can be tuned by controlling the film thickness and the excitation intensity. For sufficiently thin films the peak position of the ASE is determined by the cut-off wavelength for the waveguide and is shifted to shorter wavelengths with decreasing film thickness. Increasing excitation intensity causes a blue-shift of the emission spectra. We also show that excitation wavelength has no effect on the position of the ASE.
