Abstract： |
The present invention belongs to the field of optical fibre grating production technology. It is characterized by that said invention successively includes the following several steps: designing a nonlinear chirp optical fibre grating with tunable property, namely, its reflectivity and wavelength are formed into Gaussian curve change and its group delay and wavelength are formed into secondary curve change utilizing reconstruction principle of grating to obtain reflectivity modulation function of grating, and utilizing said function to define sampling point position and exposure time, then utilizing designed result to make a nonlinear chirp optical fibre grating for 40 G b/s optical communication system. |
