(Color online) Images and spectra for WG devices of PQR (all taken with an off-normal view angle of 15°). [(a1) and (b1)] Scanning electron microscopy (SEM) images of typical mesa and hole (cross section) PQRs. [(a2) and (b2)] Charge-coupled device (CCD) images of illuminant mesa and hole PQRs. Shaded fingers are metal electrodes. (a) Concave WG (mesa PQR) spectra showing size-dependent resonances away from critical diameter. (b) Convex WG (hole PQR) spectra without resonance enhancement.
(Color) Angle-resolved spectra of a hole among PQR hole array at /hole. (Inset) Color-coded PQR hole array emission at (total) with resonance enhancement; a magnified portion and CCD image of the illuminant hole emitters , where shaded, fingered metal grid structures are visible; SEM image of a PQR hole.
(Color) Threshold curves A and B from PQR and quantum well formulas, respectively, with corresponding Rayleigh toroid schematics (defined by Rayleigh width between and ) and transparency curve T for the PQR case. Data for transparency (empty symbols) and threshold (solid symbols) currents: circles for PQRs and squares for PQR holes. Data at and (squares) correspond to the case of hole arrays without implantation (see the arrows 1 and 2).
