Theoretical study of amplified spontaneous emission intensity and bandwidth reduction in polymer |
Plots of the ASE intensity versus excitation length. Sample thicknesses are: s = 150, 200, and 300 nm. The calculations are carried out when μ = 1 is used for H-broadening ( C 1,H-profiles). The refers to the calculation for μ = 0, with gain parameters obtained from the C 1,H-profile with s = 200 nm, and it refers to the unsaturated intensity calculation. The inset shows the chemical structure of the polymer. |
