Dielectric binary blazed gratings.
Artificial index gratings, which are composed of binary microstructures of sizes less than the incident wavelength, are analyzed as functions of the filling factor or duty cycle of the microstructures. Different models for calculating the optimum duty cycles to produce high blazed diffraction efficiency are compared. Blazed binary grating designs in a material with a refractive index n = 2 show...
متن کاملWide-band/angle Blazed Surfaces using Multiple Coupled Blazing Resonances
Blazed gratings can reflect an oblique incident wave back in the path of incidence, unlike mirrors and metal plates that only reflect specular waves. Perfect blazing (and zero specular scattering) is a type of Wood's anomaly that has been observed when a resonance condition occurs in the unit-cell of the blazed grating. Such elusive anomalies have been studied thus far as individual perfect bla...
متن کاملFabrication of High-eciency Multilayer-coated Binary Blazed Gratings in the Euv Regime
Improving the eciency of soft X-ray and extreme ultraviolet (EUV) gratings by way of multilayer re¯ection coatings has been under investigation for many years. Here we present the fabrication and characterization of binary blazed gratings designed to operate in the 14 nm wavelength region. These binary gratings are stepped approximations to the ideal sawtooth blazed-grating pro®le and are fabr...
متن کاملBlazed Gratings Recorded in Absorbent Photopolymers
Phase diffractive optical elements, which have many interesting applications, are usually fabricated using a photoresist. In this paper, they were made using a hybrid optic-digital system and a photopolymer as recording medium. We analyzed the characteristics of the input and recording light and then simulated the generation of blazed gratings with different spatial periods in different types o...
