Dispersion compensation experiments of 40 Gbit/s NRZ signal using arrayed-waveguide grating based dispersion compensator

Dispersion compensation of 40 Gbit/s, NRZ signal is successfully demonstrated. The arrayed-waveguide grating based dispersion compensator has the dispersion of 123 ps/nm, the bandwidth of 70 GHz and the insertion loss of 7.5 dB. (2 pages)
