“…Figure 13 shows our exciting experimental results where the peak reflectance reaches 100.2% normalized to bulk, deposited gold. Predicted gold reflectivity reaches 99.4% at these wavelengths so we may conclude that this device demonstrates comparable or better reflectivity than the published record of 98% 10 . The spectral FWHM is a narrow 4.14nm and perhaps more importantly, the sidebands across the wide spectral range remain low and flat (≤5%); close to our theoretical target of 4.3%.…”

This report describes a passive, optical component called resonant subwavelength gratings (RSGs), which can be employed as one element in an RSG array. An RSG functions as an extremely narrow wavelength and angular band reflector, or mode selector. Theoretical studies predict that the infinite, laterally-extended RSG can reflect 100% of the resonant light while transmitting the balance of the other wavelengths. Experimental realization of these remarkable predictions has been impacted primarily by fabrication challenges. Even so, we will present large area (1.0mm) RSG reflectivity as high as 100.2%, normalized to deposited gold.Broad use of the RSG will only truly occur in an accessible micro-optical system. This program at Sandia is a normal incidence array configuration of RSGs where each array element resonates with a distinct wavelength to act as a dense array of wavelength-and modeselective reflectors. Because of the array configuration, RSGs can be matched to an array of pixels, detectors, or chemical/biological cells for integrated optical sensing. Micro-optical system considerations impact the ideal, large area RSG performance by requiring finite extent devices and robust materials for the appropriate wavelength. Theoretical predictions and experimental measurements are presented that demonstrate the component response as a function of decreasing RSG aperture dimension and off-normal input angular incidence. 4 AcknowledgementSandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin

This paper reviews the application of photonic crystals (PhCs) and related periodic structures to spectrometers and wavelength filters. In the first half of the paper in-plane type spectrometers utilizing superprism effect are reviewed. In the latter half out-of-plane and surface-normal type devices, where guided mode resonance (GMR) plays a center role, are described. Finally, Bragg reflection type wavelength filters are dealt with.

“…A RG functions basically as a wavelength selective mirror, and its reflection spectrum can be tailored by designing the periodic structure appropriately [18]. Highly efficient reflection [19], as well as the ability to tailor the spatial beam profile, has been successfully demonstrated [20]. Recently, attempts have been made to extend the GMR concept to curved substrate structures [21,22].…”

Cylindrical Resonator Utilizing a Curved Resonant Grating as a Cavity Wall

A thin-film grating on a curved substrate functions as a highly reflective and wavelength sensitive mirror for a diverging wave that has the same curvature as the substrate. In this paper we propose a cylindrical cavity surrounded by a curved resonant grating wall, and describe its resonance characteristics. Through finite-difference time-domain (FDTD) simulation we have clarified that this type of cavity supports two resonance modes: one is confined by Fresnel reflection and the other by resonance reflection of the wall. We have also demonstrated that the latter mode exhibits a Q factor several orders of magnitude higher than that of the former mode.
