Since the 80's, specialists of gratings can rely on very powerful grating softwares [1-6].
These softwares are able to compute grating efficiencies for almost any kind of grating in any …

We present a polarization-insensitive subwavelength grating reflector based on a
semiconductor-insulator-metal structure. The polarization-insensitive characteristic …

The most important properties of diffraction gratings are revisited in view of different
applications: classical (spectroscopic, filtering, waveguiding) and modern (plasmonics …

The use of chalcogenide glassy semiconductors as an inorganic vacuum photoresist to
obtain periodic relief structures on substrates of various compositions is investigated. It is …

We propose a polarization-insensitive and broadband subwavelength grating reflector
based on a multilayer structure. The reflector has an overlapped high reflectivity (> 99.5%) …

This paper is devoted to the study of a polarization independent reflector made with a
multilayered configuration grating structure with a multi-subpart profile. Rigorous coupled …

In recent years, silicon nanophotonic devices have attracted more and more attention due to
their compactness, low power consumption, and easy integration with other functions. In …

We report the first experimental realization of total internal reflection (TIR) diffraction
gratings. Performance of less than 0.7-dB insertion loss (IL) for both TE and TM polarizations …

Three variants of binary blazed gratings with subwavelength features are considered, which
have high first-order efficiencies in the non-paraxial domain for arbitrarily polarized light. A …
