Jx. Cai et al., Simultaneous tunable dispersion compensation of many WDM channels using a sampled nonlinearly chirped fiber Bragg grating, IEEE PHOTON, 11(11), 1999, pp. 1455-1457
We fabricated and characterized a tunable dispersion compensator for multip
le wavelength-division-multiplexed (WDM) channels using a sampled nonlinear
ly chirped fiber Bragg grating. The channel dispersion can be adjusted from
-200 to -1200 ps/nm. We demonstrate tunable dispersion compensation for th
ree channels in a 10-Gb/s WDM system. All three channels achieve a BER = 10
(-9) after propagating through either 60 or 120 km of standard single-mode
fiber.
