Abstract

H-shaped oligofluorenes as gain media exhibit excellent photo- (large robustness against oxidation) and thermal stabilities in ambient atmosphere for large σ_e and low-threshold (0.22 nJ pulse^-1) deep blue distributed feedback (DFB) lasers. Their amplified spontaneous emission (ASE) thresholds increase less than 3-fold and the emission spectra exhibit almost no shift with film samples annealed up to 200 °C in open air.
