holographic grating
A holographic grating is a type of diffraction grating that is produced using holographic recording techniques. It consists of a periodic structure of alternating transparent and opaque regions,...
concave holographic grating
The generation of a grating on a concave spherical blank by the holographic process. In this way, ghost images and intense stray light are avoided.
free-space optical interconnect
A type of internal photonic connection in an integrated circuit in which a holographic grating is used to focus light at points on a silicon chip, maximizing the speed of signal propagation.
plane holographic grating
The generation of a grating on a flat surface by means of a series of interference fringes formed by a holographic process. See holographic grating.
