SPIEDigitalLibrary.orgPaper Numbering: Proceedings of SPIE follow an e-First publication model, with papers published first online and then in print and on CD-ROM. Papers are published as they are submitted and meet publication criteria. A unique, consistent, permanent citation identifier (CID) number is assigned to each article at the time of the first publication. Utilization of CIDs allows articles to be fully citable as soon as they are published online, and connects the same identifier to all online, print, and electronic versions of the publication. SPIE uses a six-digit CID article numbering system in which:The first four digits correspond to the SPIE volume number. The last two digits indicate publication order within the volume using a Base 36 numbering system employing both numerals and letters. These two-number sets start with 00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 0A, 0B … 0Z, followed by 10-1Z, 20-2Z, etc. The CID Number appears on each page of the manuscript. The complete citation is used on the first page, and an abbreviated version on subsequent pages. Numbers in the index correspond to the last two digits of the six-digit CID Number.
IntroductionOptical structures that are on the order of optical wavelength have been used to change the optical properties of the structures, similar to the use of nanostructures for quantization of electron wave. Recently, a new class of single planar layer subwavelength metastructures has emerged. The new metastructures are dielectric gratings with a large index contrast that can be designed to exhibit many extraordinary properties. For example, high contrast gratings (HCG) can provide very high reflection over a broad spectral range for light propagating in the direction orthogonal to the periodicity. It can also be designed to be a resonator with an extremely high quality factor and with user-friendly surfacenormal coupling. Furthermore, changing the grating dimension individually, an ultra-thin lens or focusing reflector with high focusing power can be obtained.This conference is the second one devoted to this theme. The presentations include a wide range of exciting advances, ranging from new physics, theories, to device applications. Various materials and fabrication technologies were used as basic platforms. In these proceedings, the readers will find discussion of novel direction selective filter elements, deep ultraviolet (DUV) polarizer and low noise infrared-mirrors. HCG designs to provide spatial mode filtering for mode control of VCSELs and wave-front-engineered mirrors are discussed. Phase engineering using HCG are explored in surface-normal transmission for solar cell concentrator optics and spiral lens applications. Using it at a glancing angle for hollow core waveguide, slow light waveguides are demonstrated. In addition, dynamically tunable all-pass filter array for fast optical beam steering is also presented.During and post conference, we received much positive ...
