    • Fibers with diameter below 300 nm show a weaker coupling of the emitted light into guided modes. This can easily rationalized since for a cylindrical waveguide of core diameter df the fractional coupled power, η, is given by η, 1, V-3[2.405exp(-V-1, 2, where V, 0.5kdf (n2-1)1/2 and k, 2π/λ. See: A. W. Snyder, D. Love, Optical Waveguide Theory, Kluver, Boston 1983. For R6G fibers (λ > 500 nm) we estimate that more than 90% of the emitted light Is coupled into the waveguide mode for df > 500 nm, whereas η, 20% for df=150nm
