Abstract :
We experimentally investigate the influence of frequency mismatch in all-optical orthogonal frequency-division multiplexing (OFDM) system with arrayed waveguide gratings (AWGs). The experimental results show that frequency mismatch should be kept within the range of ±4% of channel spacing to keep the bit error rate (BER) under 10-5.
