title: Very high-quality distributed Bragg reflectors for organic lasing applications by reactive electron-beam deposition.
abstract: We report on the realisation of a few pairs dielectric Distributed Bragg Reflectors fabricated by reactive electron-beam deposition, with state-of-the-art performances, such as very high reflectance (up to about 99.4%), wide stop band (up to 160 nm) in the visible range, and smooth interfaces (roughness as low as 1.5 nm). As a demonstrator of the very high quality of the mirrors we realized a polymer-based vertical microcavity laser by an imprinting-like approach. The device exhibits laser action at 519 nm, indicating low-loss dielectric reflectors grown by electron-beam techniques as promising tools for organic solid-state lasers.
