Polarization insensitive blazed diffraction gratings [PDF]

Journal of the European Optical Society-Rapid Publications, 2006
Gratings insensitive to light polarization may be useful in many areas of optical engineering, particularly in light demultiplexing application. We study different kinds of binary gratings able to present reflected efficiencies higher than 98% in the ...

Resonant diffraction gratings with polarization-dependent efficiencies [PDF]

EPJ Web of Conferences, 2020
Subwavelength-structures with different fill factors in the lateral dimensions result in unique phase shifts for the different polarization states of transmitted light. By using this additional degree of freedom for diffractive optical elements, we yield

Tailorable Elastomeric Grating With Tunable Groove Density Gradient

IEEE Photonics Journal, 2017
This paper describes a new method for fabrication of tailorable elastomeric gratings with tunable groove density gradients based on stretching of the grating sample in a direction perpendicular to the grating line within the grating surface.
