Image of FIG. 1.
FIG. 1.

(a) A schematic of the SRR on top of a QW [the dimensions are shown in Fig. 3(c)], and its calculated transmission spectrum (b). The dashed curve is the calculated transmission through a closed square loop on top of the QW sample. The arrow points at the frequency at which (c)–(g) were calculated. (c)–(g) Cross sections of the z-component of the electric field parallel to the axes indicated on each figure. The color bars indicate the ratio between the shown field and the incident field (polarized in the y direction). (c) Located in center of the gap in the x direction. [(d) and (e)] Located 15 nm and 65 nm away from the SRR/sample interface into the sample, respectively. (f) and (g) are the same as (d) and (e) but calculated for the closed square loop instead of a SRR.

FIG. 2.

(a) The layer sequence of the QW sample. (b) An energy band diagram of two asymmetric coupled QWs. The subbands and their corresponding wave functions (modulus) are shown as well. (c) A SEM image of representative SRRs.

Image of FIG. 3.
FIG. 3.

[(a)–(c)] Transmission spectra for three different SRR arrays, which were scaled (length, linewidth, gap size, and periodicity) to resonate at different frequencies. (a)–(c) are scaled by 0.9, 1.0, and 1.1, respectively. The legend indicates the polarization of the incident light for each transmission line and the substrate beneath the SRRs.

Image of FIG. 4.
FIG. 4.

[(a)–(c)] Experimental and calculated transmission spectra for three different SRR arrays located on the QW sample, which were scaled (length, linewidth, gap size, and periodicity) to resonate at different frequencies. The legend indicates the polarization of the incident light for each transmission.
