title: Enhanced two-photon biosensing with double-clad photonic crystal fibers.
abstract: A double-clad photonic crystal fiber was used to improve detection efficiency over a standard single-mode fiber in a two-photon fluorescence detection scheme in which the dye was excited and the fluorescence was detected back through the same fiber.
