H. Takenouchi et al., 8THz bandwidth dispersion-slope compensator module for multiband 40 Gbit/sWDM transmission systems using an AWG and spatial phase filter, ELECTR LETT, 37(12), 2001, pp. 777-778
The authors demonstrate a 2 x 40-channel dispersion-slope compensator for 4
0Gbit/s wavelength-division multiplexing (WDM) transmission systems that em
ploys an arrayed-waveguide grating (AWG) with a 4.0THz bandwidth and a spat
ial phase filter. It can compensate for the dispersion slope of the entire
bandwidth of C- and L-bands simultaneously.
