TL;DR: An electro-optic waveguide device (10) comprises an assembly of waveguides (30) connected to a common light input region and forming a common far field diffraction pattern (44) as mentioned in this paper.

TL;DR: In this article, the authors proposed an electro-optical waveguide device which is made extremely smaller in size as compared with the prior art and is improved in performance by incorporating a waveguide core layer 18 sandwiched between two light confinement layers 16, 32 having a low refractive index.

TL;DR: The behavior of optical diffraction gratings which have been weighted in various ways analogous to those used in surface acoustic wave devices are described, and the factors that limit the performance achievable in practice are described.
