“…To attain this end plasmonic and diffractive nanostructures, down-converting particles, surface texturing, nanohole patterning etc. are widely studied [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In this investigation we examine the possibility to enhance light absorption by particulate active layer.…”

“…Two dimensional (2D) photonic crystals and 2D PhC slabs are of particular interest since several fabrication methods are currently available for this kind of structures. Many applications have been suited to one dimensional (1D) and two dimensional (2D) photonic structures such like antireflective coatings (Domínguez et al, 2012), band pass filters (Robinson & Nakkeeran, 2012), electro-optical sensors (Yang, Tian & Ji, 2011), switches (Rahmati & Granpayeh, 2011), light extraction on LEDs (Zhmakin, 2011) and power splitters (Esmaieli & Ghayour, 2012) just to mention some of them. New applications based on photonic crystals have played a very important role in new advances to develop ultimate technology.…”

Hybrid two-dimensional photonic crystal structure described by a square lattice of circular air columns with embedded quasi-circular micro-cavities in a square array was fabricated on Si-ZnO substrate using the focused ion beam (FIB) technique. The optical characterization of this photonic device revealed its ability to selectively enhance the reflectance on specific wave lengths in the border of visible-near-infrared range (VIS-NIR). The behavior of the photonic hetero-structure built and studied in this work was attributed to the coupling of the probe light beam with the embedded micro-cavities in the regular square lattice of air columns describing the photonic crystal. The results obtained in this work suggest the presence of a photonic band gap around the border of VIS-NIR range in the studied hybrid photonic structure. RESUMENSe fabricó una estructura fotónica híbrida bi-dimensional mediante el método de haz enfocado de iones (FIB), descrita por una red cuadrada de columnas circulares de aire con un patrón de micro-cavidades cuasi-circulares embebido, describiendo un arreglo cuadrado en un sustrato de Si-ZnO. La caracterización óptica de este dispositivo fotónico reveló su habilidad para mejorar selectivamente la reflectancia en longitudes de onda específicas en el borde de los rangos visible-infrarrojo cercano (VIS-NIR). Este comportamiento de la hetero-estructura fotónica construida y estudiada en este trabajo se atribuyó al acoplamiento del haz de luz de prueba con las micro-cavidades embebidas en la red cuadrada regular de columnas de aire que describen el cristal fotónico. Los resultados encontrados en este trabajo sugieren la presencia de una brecha fotónica prohibida alrededor de la frontera del rango VIS-NIR.

“…1-3 Due to the subwavelength feature size, nanostructures behave as an effective medium with a gradient refractive index, suppressing light reflection at material interfaces through adiabatic impedance matching. 1,2,[4][5][6] In the case of silicon, many efforts have been undertaken to improve light absorption by texturizing the surfaces. Previous reported solutions achieved reflectance under 1% in the visible wavelength region, but extending these properties to broader bands remained challenging.…”

In this work, the authors present a novel fabrication process to create periodic nanostructures with aspect ratio as high as 9.6. These nanostructures reduce spectral reflectance of silicon to less than 4% over the broad wavelength region from 200 to 2000 nm. At the visible range of the spectrum, from 200 to 650 nm, reflectivity is reduced to less than 0.1%. The aspect ratio and reflectance performance that the authors achieved have never been reported before for ordered tapered nanostructures, to our knowledge.
