Abstract :
A novel tunable grating exhibiting a linear dispersion in a channel is designed and fabricated for the first time. The equivalent chirp is formed through chirping of the sampling function in a sampled Bragg grating. The sampling period is in the order of millimeter, which can be easily controlled. By employing the tunable grating, the dispersion of 50-km single-mode fiber is completely compensated in a 10-Gb/s transmission with a power penalty of -0.7 dB.
