Approaches for the RCWA-based non-destructive characterization of subwavelength-structured gratings

چکیده
Nano-structuring enables us to add additional degrees of freedom the design optical elements. Especially possibility controlling polarization is great interest in field nano-structured optics. For being able exploit whole range form-birefringent phase shifts, aspect ratios resulting element are typically much higher than conventional diffractive elements (DOEs), which does not only pose a challenge on fabrication but also characterization. We evaluate several well-established approaches for nondestructive characterization, including Müller-Matrix-Ellipsometry, measurement diffraction efficiencies, scattering measurements and calibration with rigorous coupled-wave modelling. The goal understand challenges all these techniques combine them reliable method structural reconnaisance high ratio nanostructures.

NON-DESTRUCTIVE THERMAL DAMAGE CHARACTERIZATION OF CORDIERITE-MULLITE REFRACTORIES
Abstract: Refractory materials containing cordierite (2MgO.2Al2O3.5SiO2) and mullite (3Al2O3.2SiO2) are used as support in furnaces, because of their low thermal expansion properties which confer them a very good ability to thermal shock resistance. Composed of two phases presenting very different CTE (1.5–3×10-6 for cordierite and 4–6×10-6 K-1 for mullite), these materials can develop damag...
متن کاملSubwavelength surface-relief gratings for stellar coronagraphy.
We present a new design of a phase mask coronagraph implemented with subwavelength diffractive optical elements consisting of optimized surface-relief gratings. Phase mask coronagraphy is a recent technique that seeks to accommodate both high dynamic and high angular resolution imaging of faint sources around bright astrophysical objects such as exoplanets orbiting their host stars. The origina...
