The effect of varying film thickness (h) on the amplified spontaneous emission (ASE) properties of 0.5  wt.% perylenediimide-doped polystyrene waveguides is reported. The threshold dependence on h, not previously investigated in detail, is analyzed in terms of the film absorption and photoluminescence, the confinement of the fundamental waveguide mode (TE0), and the presence of high-order modes. For h<400  nm and down to 150 nm, the ASE wavelength blueshifts, while the linewidth and threshold… CONTINUE READING
