Image of FIG. 1.
FIG. 1.

UV-visible absorption (dashed) and photoluminescence (solid) spectra of the RhB-doped PMMA film under excitation wavelength of . The inset shows the chemical structure of RhB.

FIG. 2.

(Color online) (a) Transmission spectrum of the opal PhC, relative to the normal of (111) planes of opal PhCs. The inset shows the SEM image and digital camera photo of the opal PhC, and the scale bar is . (b) Schematic configuration of the “sandwich” structure. Incident angle and detection angle are 50° and 0°, relative to the normal of (111) planes of the opal PhCs.

FIG. 3.

(a) Emission spectra of the RhB-doped PMMA film without opal PhCs pumped by /pulse at (A) and RhB-doped PMMA film with opal PhCs pumped by 48 and /pulse (B and C) as well as the transmission spectrum of the opal PhC. (b) Emission spectra of RhB-doped PMMA film with opal PhCs at various pumping energies. The inset shows output emission intensities (squares) of RhB-doped PMMA film and the FWHM (circles) of the ASE spectra under various pumping intensities.
