FIG. 1.

(a) Near-field spectrum of the single D2 PC-MC (averaged on a region of ). [(b)–(d)] PL intensity maps associated to the M1-M3 modes; the holes surrounding the D2 defect are reported as white circles. [(e)–(g)] Spectral shift maps associated to the M1-M3 modes; in particular the maximum spectral shift in (e) and (f) is 0.2 nm, while in (g) is 0.5 nm. [(h)–(j)] Calculated electric field distribution of the M1-M3 modes at 30 nm above the photonic membrane. (i) Topographic map as obtained during the SNOM scan. All the maps in (b)–(j) have the same spatial extension .

FIG. 2.

(a) Near-field spectrum of the horizontally coupled D2 PC-MCs (averaged on a region of ). Inset (i): topographic map as obtained during the SNOM scan. [(b)–(e)] PL intensity maps associated to the peak P1-P4. [(f)–(i)] Spectral shift maps associated to the peak P1-P4; in particular the maximum spectral shift in (f) and (g) is 0.3 nm, in (h) is 0.5 nm, and in (i) is 0.2 nm. [(j) and (k)] Calculated electric field distribution of P3 and P4 at 30 nm above the photonic membrane. All the maps have the same spatial extension .

FIG. 3.

(a) Near-field spectrum of the vertically coupled D2 PC-MCs (averaged on a region of ). Inset (i): topographic map as obtained during the SNOM scan. Inset (ii): near-field high resolution spectrum that resolves the contributions of P3 and P4. [(b)–(e)] PL intensity maps associated to the peak P1-P4. [(f)–(i)] Spectral shift maps associated to peak P1-P4; in particular the maximum spectral shift in (f) and (g) is 0.15 nm, in (h) is 0.2 nm, and in (i) is 0.1 nm. [(j) and (k)] Calculated electric field distribution of P1 and P2 at 30 nm above the photonic membrane. All the maps have the same spatial extension .
