Polymeric demultiplexer component for wavelength division multiplex communication systems using polymer fibers

Data communication over Polymer Optical Fibers using Wavelength Division Multiplexing, offer high extension capabilities for the overall data rates. Here, a de/multiplexer as a key component was developed im PMMAusing an optical grating placed on an aspheric mirror by injection molding. A demonstrator is fabricated by directly machining it in the PMMA material by means of diamond turning technique. The paper presents the results of the different simulations followed by the development steps and the measurements done with the first demonstrator accompanied by the first BER measurements using a 4 channel WDM transmission The record 8.26 Gb/s data transmission based on the offline-processed discrete multitone modulation technique has been demonstrated over 100-m SI-POF at a bit-error ratio of 10-3.
