A GeSbTe (GST) lamellar diffraction grating placed on a silicon-on-insulator waveguide is considered as a potential component of a photonic non-volatile memory cell. Unlike a continuous film the ...

The diffraction efficiency of reflection volume holographic grating of different thickness at different locations in the off-axis recording (, ,). When the thickness of grating is 60 μm, the ...

Using only a single-crystal piezoelectric thin wafer of lithium niobate (LN) instead of the usual two-part structure, a group ...

Researchers from the Illinois Grainger College of Engineering are the first to demonstrate a simple and tunable method for ...

Abstract: The diffraction of a plane electromagnetic wave by a thick strip grating is solved rigorously by the Wiener-Hopf technique. The solution contains an infinite number of unknowns, which are ...
