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.

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.

This paper introduces, in detail, the form, basic principle, properties, fabrication of the UV written chirped fiber grating and its typical application to optical communication.
