Broadband Fluorescence Guided-Wave in DANS/PMMA Thin Film Waveguides

The broadband fluorescence guided-waves excited in DANS/PMMA polymer thin film waveguides by an Ar⁺ laser beam were demonstrated in terms of the observation of mlines with colour array. Considering the high brightness of these m-lines observation, we assert that it is a kind of stimulated amplification of fluorescence guided-wave.
