Optically pumped surface-emitting lasing using self-assembled block-copolymer-distributed Bragg reflectors. Academic Article uri icon


  • A thin-film organic laser cavity using a block-copolymer-based one-dimensional (1D) photonic crystal was fabricated. Polymeric distributed Bragg reflectors (DBRs) were prepared through the self-assembly of a lamellar-forming poly(styrene-b-isoprene) (PS-b-PI) diblock copolymer having a 1D photonic stop band overlapping with the fluorescence spectrum of a gain medium. Optically pumped surface-emitting lasing was obtained using poly(methyl methacrylate) (PMMA) doped with 1,4-di-(2-methylstyryl)benzene (Bis-MSB) as an organic gain medium and the polymeric self-assembled DBR as a spectral-band selective feedback element.
