Abstract

A four-channel substrate wavelength-division (de)multiplexer based on superimposed holographic gratings, three-dimensional Bragg diffraction, and substrate wave propagation is demonstrated. The device operates at the He–Ne laser wavelengths of 543.0, 594.1, 611.9, and 632.8 nm and has a measured maximum diffraction efficiency of 72% with less than −30 dB of channel cross talk. It is shown that the polarizations of the demultiplexed beams can be controlled by the grating index modulation, as predicted by holographic diffraction theory. The substrate wavelength-division (de)multiplexer device, whose demultiplexed signal propagation directions can be defined during fabrication, should find widespread use in integrated fiber-optic communication networks and systems.
