Characterization of Shaping Filter Employed in All-Optical Generation of UWB Pulses
In this paper, we investigate the effect of varying the bandwidth of shaping filter on bit error rate (BER) performance of ultra-wide band over fiber (UWBoF) system. UWB mono-cycle pulses are all-optically generated by exploiting the cross-phase modulation effect in highly non-linear fiber (HNLF) followed by phase modulation (PM) to intensity modulation (IM) conversion and then transmitted over 20 km single mode fiber (SMF) towards remote radio access unit (RAU) where the pulses are photo-detected. By varying the bandwidth of shaping filter from 25 GHz up to 125 GHz in steps of 25 GHz, corresponding BER plots are obtained. Simulation results show that performance degrades in terms of minimum receiver sensitivity while increasing the bandwidth of the shaping filter. We further investigate the dependence of width tuning of generated UWB mono-cycle pulses on chirp swing and shaping filter bandwidth. Simulation results show that width tuning saturates when chirp swing exceeds the bandwidth of the shaping filter.
