Figure 1 Schematic diagram of a three-dimensional integrated multichannel waveguide grating filter: (a) 1:1 planar beam splitter, (b) 1:1 three-dimensional beam splitter, (c) waveguide gratings ...
Researchers have succeeded in making the thinnest ever optical device in the form of a waveguide just three atomic layers thick. The device could lead to the development of higher density ...
