FIG. 1.

(a) Spectral shift of the photonic molecule peaks as a function of the number of hole planes between the two cavities, calculated by a two-dimensional FDTD model. The black-gray (red) circles represent the symmetric-antisymmetric modes. The small dots are the averaged spectral shifts of the mode of the 550 nm cavity when coupled with either 500 or 600 nm cavities, and they represent the nonresonant mode shift. (b) SEM image of the studied sample, with three hole barrier separation. [(c) and (d)] Spatial distribution of the electric field intensity associated to the symmetric and antisymmetric mode, respectively, as calculated by 3D FDTD model.

FIG. 2.

(a) Schematic description of the tuning method. (b) FDTD calculations for different infiltration configurations. (c) FDTD calculations for different fine tuning configurations. The evaporation is simulated by reducing the refractive index of the infiltrated material. The value of the refractive index is decreased from (filled cavity) to (empty cavity).

FIG. 3.

The two top panels show the photoluminescence map for the two modes of the system at short (S) and long (L) wavelengths. In the low panel the spectra for different positions (step of 200 nm) along the vertical direction of the photonic molecule are reported. The SEM images reported in the low panels are scaled in order to give the spatial position of each spectrum. (a) Data after the infiltration process. (b) Data at zero detuning. (c) Data with negative detuning.

Image of FIG. 4.
FIG. 4.

Peaks position behavior during the detuning variation via local heating. Dotted lines are fits of the mode energies far from the coupling region. Inset: mode splitting as a function of Δ, as estimated from the fits.
