Paper Abstract

POFs (polymer optical fibers) replace the established communication media as copper and glass step by step in short distance communication systems, because of their economical and easy-manageable advantages. POFs are used in various fields of optical communication, e.g. the automotive sector or for "Triple-Play" in the in-house communication. The state of the art technology are single mode communication systems. The using of only one wavelength for communication limits the bandwidth. For future scenarios this technology is the shortage of bandwidth, e.g. for HDTV with IP-TV. One solution to breakthrough this limitation is to use more than one wavelength over one single fiber, this is so-called WDM (wavelength division multiplexing). But this multiplexing technology requires two more technical keyelements: a multiplexer, which combines the multi-wavelengths signals into one fiber and a demultiplexer at the end of the network to separate the colored signals. In this paper computer simulations of the design of different WDM keyelements are shown. The basic concept is a grating on a higher-order mirror to combine and separate the multi-colored channels. The following realization of the demultiplexer is planed to be done with injection molding. This technology offers easy and very economical processing. These advantages make this technology first choice for optical components in the low-cost array. All components can be fabricated by means of injection molding and micro injection molding. First promising prototypes of this manufacturing technology are presented in this paper as well.
