Compact multichannel demultiplexer for WDM-POF networks based on spatially overlapped FBGs
The fabrication of spatially overlapped fibre Bragg gratings over microstructured polymer optical fibre allows to demonstrate low-cost and compact multichannel wavelength division demultiplexers. Coarse and dense wavelengths in high-capacity optical systems have been demonstrated for reduced size environments with the advantages of polymer fibres.
