Micro-structured Optical Spectrometer Sensor in PMMA
Data communication over Polymer Optical Fibers (POF) is limited to only one channel for data transmission. Therefore the bandwidth is strongly restricted. By using more than one channel, it is possible to break through the limit. This technique is called Wavelength Division Multiplexing (WDM). It us...

| Summary: | Data communication over Polymer Optical Fibers (POF) is limited to only one channel for data transmission. Therefore the bandwidth is strongly restricted. By using more than one channel, it is possible to break through the limit. This technique is called Wavelength Division Multiplexing (WDM). It uses different wavelengths in the visible spectrum to transmit data parallel over one fiber. Two components are essential for this technology: A multiplexer (MUX) and a demultiplexer (DEMUX). The multiplexer collects the light of the different sources to one fiber and the demultiplexer separates the light at the end of the fiber into the different fiber output ports. In this paper, we show the realization of a grating spectrometer realised by injection moulding in PMMA, working in the visible spectrum, respectively. We present the results of a demonstrator of an integrated polymeric spectrometer device produced with injection moulding in combination with hot embossing. The paper discusses the results of the different development steps, the measurements done with the first demonstrator and the challenges related to the injection moulding process. |
