We numerically study the characteristics of optical transmission of metallic nanoslit arrays (MNSAs) with embedded microcavities (MC-MNSAs) and demonstrate that passbands of the transmission spectra can be monotonously tuned by adjusting the dimensions of the microcavities. The study discloses that spectra of conventional MNSAs and MC-MNSAs are determined mainly by cavity resonances of the slits or embedded microcavities, modified by in-plane surface-plasmon wave resonances. It is also found that coupling of cavity resonances between neighboring slits or microcavities has considerable effects on the passbands. The MC-MNSA structure is shown to have potentials in applications of tunable filter arrays.

  10. The numerical calculations were performed with the software FullWAVEtrade (ver. 6.0, RSoft Design Group, Inc.), which is based on the finite-difference time-domain method. In simulations, the periodic boundary conditions were applied in the periodic direction (x direction), and perfect-matching layer boundary conditions were applied in nonperiodic directions (x and/or z direction). Permittivity of silver is defined in the software as a sum of Lorenzian functions: ε(ω)=ε∞+∑kΔεk/[ak(iω)2−bk(iω)+ck], where ε∞ is the value of permittivity in the limit of infinite frequency ω (unit, rad/μm), Δεk is the strength of each resonance, and ak, bk, and ck are fitting coefficients.
  11. The cavity intensity is calculated as the field intensity ∣Hy∣2 integrated over the area of the monitor located in the cavity.
