Here we report on low-threshold blue lasing from fully-transparent nanostructured porous silicon (PSi) monolithic microcavities (MCs) infiltrated with a polyfluorene derivative, namely poly(9,9-di-n-octylfluorenyl-2,7-diyl) (PFO). Single-mode blue lasing is achieved at the resonance wavelength of 466 nm, with line width of ∼1.3 nm, lasing threshold as low as 5 nJ (i.e. fluence of 15 μJ/cm2), and good stability under operation (i.e. 40% decay in intensity after about 7 ×105 pulses at 50 nJ).

Abstract
Here we report on low-threshold blue lasing from fully-transparent nanostructured porous silicon (PSi) monolithic microcavities (MCs) infiltrated with a polyfluorene derivative, namely poly(9,9-di-n-octylfluorenyl-2,7-diyl) (PFO). Single-mode blue lasing is achieved at the resonance wavelength of 466 nm, with line width of ∼1.3 nm, lasing threshold as low as 5 nJ (i.e. fluence of 15 μJ/cm2), and good stability under operation (i.e. 40% decay in intensity after about 7 ×105 pulses at 50 nJ).File in questo prodotto:
