Paper Abstract

Due to their economical and easy-manageable advantages, POFs (polymer optical fiber) are going to replace traditional communication media such as copper and glass step by step within short distance communication systems. POFs are already used in various fields of optical communication, e.g. the automotive sector or in-house communication. Though single channel communication systems are state of the art technology, using of only one channel/wavelength for communication limits the bandwidth. For future scenarios this traditional technology is the bottleneck of bandwidth, particularly for HDTV with IP-TV. One solution to breakthrough this limitation is to use more than one wavelength over one single fiber, this is called WDM (wavelength division multiplexing) and is well-established for GOF communication. This technique will be adapted for the visible spectrum for POF. However this multiplexing technology requires two more key-elements: a multiplexer, which combines the multiple wavelengths signals into one fiber, and a demultiplexer at the end of the network to separate the colored signals. In this paper, the development of this key-element based on a Rowland spectrometer will be shown. It starts with the simulation, this is done by means of raytracing. Also the next process steps and solutions for injection molding are described.
