By simultaneously transmitting multiple channels over a single fiber optic cable, data rates can be increased significantly. Wavelength Division Multiplexing (WDM) implements this idea technically. Considering optical long-distance communication via glass fiber, the concept of WDM is well established and components are commercially available. On the other side, optical short-distance communication via optical polymer fibers (POF) lack the availability of WDM, which leads to a much smaller available bandwidth. Within the “Opti-AWG 3D” project at Jade University of Applied Sciences in Wilhelmshaven, a WDM for POF is being developed. The design will be based on an Arrayed Waveguide Grating (AWG). Due to different properties of polymers, a complete redesign of glass-based WDM is necessary. To realize this project, ray-optical as well as wave-optical simulations are conducted. Different approaches for the calculation and simulation of multimode AWG are investigated. |
