| Abstract: | Ultrashort pulse compression by propagation in one-dimensional inhomogeneous photonic crystals with symmetric and asymmetric refractive index profiles are studied by using the transfer matrix method and Fourier analysis. The effect of different parameters, like chirp value of the incident pulse, angle of incidence, and number of unit cells on the compress factors, are investigated and temporal evolution of the reflected pulse is calculated. Compress factors as low as 32% for a sinusoidal profile are obtained using this structure. |
