Demultiplexadores para WDM sobre fibras ópticas plásticas com base em filtros gel

This work of Scientific Initiation describes the development of demultiplexers (DEMUXs) for wavelength- division multiplexing (WDM) over PMMA (poly-methyl- metacrylate) plastic optical fibre links using visible laser diodes. The DEMUXs were built from the combination of POF-splitters with gel plastic filters. The latter operates as high-pass or band- pass optical filters, are practical, simple, malleable and cost- effective. The filters can be spectrally tuned by mixing and stacking plastic layers with different colors and thickness.
