Abstract

Standard polymer optical fibers (POFs) are used in various fields of applications. As a medium for communication systems, they offer many advantages in comparison with copper or glass. POFs are applied for short-distance communication in the automotive. They are also used for communication in the house. All these applications have high demand on bandwidth. Standard communication via POF is limited in bandwidth, because only one wavelength is used to carry information over the fiber. One promising attempt is to use wavelength division multiplexing (WDM). There instead of one wavelength many wavelengths carry information over one single fiber. So WDM over POF has the power to force this limitation. Therefore the design and the development of a demultiplexer, which is required for WDM, will be shown in the paper. The development is done by means of an optical simulation program. This is a fast and inexpensive way to obtain satisfying results. The principle structure of the MUX/DEMUX element is a Rowland spectrometer. This device separates the monochromatic parts of light by means of a high dispersive grating on a mirror. The shape of the mirror and the parameters of the grating have to be developed and optimized in several steps to reach the demands. These process steps will be presented.
