We report here on applications of computer-generated holograms in fiber optical communication with modedivision multiplexing. It is shown that a pair of multichannel spatial filters matched to spatial modes provides a viable solution for transmission of several temporal signals of the same wavelength in a sole multimode fiber. Spatial filters for combining and decomposition of modes were designed, analyzed, fabricated with diffractive optics technology, and optically evaluated. (C) 2016 Optical Society of America
