Abstract

Radio over free space optics (Ro-FSO) systems have previously relied on the signal intensity, wavelength and polarizationfor multiplexing data streams in order to increase to the signal quality and achievable link range. This work leverages onoptical space division multiplexing by using novel three-core photonic crystal fiber (PCF) mode group multiplexers andhexagonal mid-gapped tiered PCF mode group equalizers for improving the signal quality and increasing the achievablelink range in a rural environment. At the transmitter, a three-core PCF mode group demultiplexer converts the fundamentalmode into three distinct mode groups used as carriers for independent transmission of three radio frequency signals. At thereceiver, the three PCF successfully equalizes the power from the received signal, with the channel impulse responsesshowing an improvement in the signal quality. An increment between 13.6% and 31.1% in the achievable link range for allchannels is evident under medium and heavy fog conditions at the same bit error rate level, using the designed PCF modegroup multiplexers and equalizers.
