Abstract :
We demonstrate that a nonlinearly chirped fiber Bragg grating can compensate RF power degradation in subcarrier-multiplexed (SCM) systems that is caused by fiber dispersion. Our all-optical technique provides tunable dispersion that compensates for multiple SCM channels simultaneously. We achieve RF-power-fading compensation for two SCM/BPSK 156-Mb/s channels in which the fading is reduced from 15 and 6 dB, respectively, to <0.5 dB for each channel.
