In the paper,a method of chirped return - to - zero(CRZ) code modulated generation was described, the CRZ code\'s characteristics on spectra domain were introduced,and the performance of the optical transmission systems using the CRZ code for different chirp modulation depth and different dispersion compensation fiber length were simulated and analyzed.

Theoretical Analysis of Linearly Chirped Moiré Fiber Gratings;

A numerical study of multi-quantum-well passively mode-locked laser diodes is presented with special attention to the chirping characteristics and its causes.

A kind of uniform density and thickness isosceles triangle cantilever beam is designed to realize linear tuning of Bragg wavelength of fiber grating without chirping by adjusting the deflection of the free end that is the vertex part of the triangle.

As in the case of conventional laser diodes,direct modulation of quantum well laser diodes brings about chirping,which effects the perfomance of optical transmission systems.

Based on repeated exposure study of chirped fiber grating

Through changing the length of the grating,modulating the amplitude of the refractive index,changing the apodized functions,changing the chirped parameters we can get different reflective spectrums with different reflective peaks and bandwidths.
