Image of FIG. 1.
FIG. 1.

(Color online) (a) Schematic diagram of double-layered CLC mirror and its photograph. (b) Transmittance and reflectance spectra of the double-layered (L- and R-helix) CLC mirror. (c) Molecular structure of the dye used.

Image of FIG. 2.
FIG. 2.

(Color online) (a) Emission spectrum from dye-doped CLC with Ag and double-layered CLC mirrors. Transmittance spectrum of a double-layered CLC, reflectance spectrum of a dye-doped CLC, and fluorescence spectrum of MEH-CN-PPV are also shown. (b) Emission spectrum from dye-doped NLC devices with Ag and double-layered CLC mirrors. Multiple lasing emission is observed. (c) Emission spectra from a dye-doped CLC device without mirrors. ASE is observed. (d) Polarization characteristics of the dye-doped CLC device with Ag and double-layered CLC mirrors.

Image of FIG. 3.
FIG. 3.

(Color online) (a) Absorption (brown) and fluorescence (red) spectra of the dye used. For a solid state device [see inset in (b)], i.e., a double-layered CLC film on which a dye molecular film was spin coated and then Ag was vacuum evaporated, emission spectra (orange and black) are influenced by the reflection spectrum of the double-layered CLC (blue curve). ASE (black) is observed when input power is above threshold. (b) Threshold behavior of the solid state device shown in the inset.
