Paper Abstract

Polymer optical fibers replace the traditional communication media as copper and glass in short distance communication systems step by step, because of their economical and easy-manageable advantages. POFs are used in various fields of optical communication, e.g. the automotive sector or the in-house communication. The best available technologies are single mode communication systems. The use of only one wavelength for communication limits the bandwidth. For prospective scenarios, this traditional technology is the bottleneck of bandwidth, e.g. for HDTV with IP-TV. One solution to overcome 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 technical key-elements: 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 simulation of the design of several demultiplexer patterns will be shown. The following realization of the demultiplexer will be done using injection molding. This technology offers easy and very economical processing. These advantages make this technology the first choice for optical components in the low-cost array. All components, the dispersive units and focusing elements, can be fabricated by means of injection molding and microinjection molding.
