Figure 1

Diagrams of various waveguide-resonator setups. (a) EIT setup, (b) conventional waveguide-cavity setup, (c) two-waveguide–single-resonator setup, (d) parallel waveguides setup. Blue and red color mapping shows the magnitude of the electric field (positive and negative values). The frequency for each plot is chosen near the resonance near $0.64c/a$. Green and orange arrows denote input and output (transmission) ports, respectively.Reuse & Permissions

Figure 2

Calculated results for configuration in Fig. 1b as a function of the distance $d$ between either waveguide-resonator or waveguide-waveguide. (The waveguides have a radius $r=a=1\mu$m, a width of $0.2a$, ${\epsilon }_{\mathrm{Si}}=12.1$, surrounded by air, ${\epsilon }_{\mathrm{air}}=1$. The resonator has resonance near $0.64c/a$.) (a) Pressures: waveguide-resonator pressure $F_{\mathrm{wr}}$ for $L={\lambda }_w,4{\lambda }_w,7{\lambda }_w$ (solid, dashed, dash-dotted lines, respectively) and waveguide-waveguide pressure $F_{\mathrm{ww}}$ (dotted line). (b) Waveguide-resonator coupling rates: $1/{\tau }_e$ (solid) and $1/{\tau }_0$ (dashed). (c) Resonator field enhancement $\mathcal{F}$.Reuse & Permissions

(a) Transmission as a function of frequency, for the two-waveguide-single-resonator setup with $L={\lambda }_w$, $d=0.1a$. (b) Transmission for the two-resonator-two-waveguide setup with $w=4.03a$ (solid). (c) $T$ and (d) $F_{\mathrm{wr}}$ as a function of frequency for the two-resonator setup with the same $L$ and $d$ for $w=3.95a$ (red), $3.97a$ (yellow), $3.99a$ (green), $4.01a$ (blue), and $4.03a$ (black).Reuse & Permissions

(a) $F_{\mathrm{wr}}$ for the two-resonator setup as a function of $w$, with the same parameters as in Fig. 3. The pressure for the two-waveguide-single-resonator setup (dashed) and the pressure for a one-waveguide-single-resonator system (dash-dotted), for the same $L$ and $d$, are also shown for comparison. (b) ${\mathcal{F}}^2$ for the same setup as (a).Reuse & Permissions
