چکیده
Photograph of a mechanically flexible 2D-DFB laser made from the conjugated polymer MeLPPP. The laser is optically pumped well above the threshold for amplified spontaneous emission. The complex far-field emission pattern (blue-green) results from a large detuning between the resonance wavelength and the gain maximum. • A nearly diffraction limited surface emitting conjugated polymer laser utilizing a 2D photonic bandstructure • Lasing modes in organic solid state distributed feedback lasers • Very compact tunable solid-state laser utilizing a thin-film organic semiconductor • Picosecond amplified spontaneous emission bursts from a molecularly doped organic semiconductor
