Inhalt:
In this work silicon multi-segment photo detectors are analyzed for their suitability as mode demultiplexing devices in multi-mode multiple-input multiple-output (MIMO) transmissions. Therefore, different chips are characterized with respect to their local responsivities and segment’s bandwidths. The fiber alignment and packaging process of the detector are presented. By using a two-segment detector a (2x2) MIMO transmission over 1 km multi-mode fiber at 850 nm operating wavelength is formed and characterized by its specific impulse responses as well as the bit-error rate performance capabilities. The results show that multi-segment detectors are suited for simple and efficient mode demultiplexing in a multi-mode MIMO system.
