摘要
A novel method utilizing a cantilever beam to tune the center wavelength and the linear chirp of fiber gratings is presented. Based on this method, the center wavelength and the chirp of a 10cm uniform fiber grating are tuned to compensate for the dispersion of 19 ps pulse width after 133 km transmission. Experimental results show that the effect of dispersion compensation is favorable.
