Abstract :
The chirping mirrors with chirping at both high and low refractive index layers are investigated using the transfer matrix method. The results show the negative and slightly constant group delay dispersion with an absolute value 16.7 fs/sup 2/ at the Bragg wavelength for the fourth-order chirping mirrors. These results allow further investigation of the light propagation in asymmetrical periodical structures and pulse reflection from new types of mirrors.
