Schematic of a laterally structured organic MC.
Emission spectra of a laterally patterned MC as a function of pump power above lasing threshold . The sharp features of the lower spectrum represent lasing from the principal modes [(1,1) modes] of three different photonic dots labeled A, B, and C. Lasing from higher order modes is clearly resolved at higher excitations (upper spectrum).
Emission spectra shown for the A (a) and B (b) photonic dots. The dotted lines mark the free-space wavelengths of the modes, calculated according to Eq. (1). The corresponding pairs of wave numbers are shown in brackets.
Comparison of output emission intensities (a) and FWHM (b) as a function of pump energy density in patterned [mode (1,1) of dot A] and unpatterned structures. Pump energy density and output intensity for the patterned structure (open circles) are scaled arbitrarily to emphasize the difference between the spontaneous emission coupling factors.
