Transmission Spectra of Quantum Well of Photonic Crystals with Negative Dielectric

The transmission spectra and dispersion relationship of the model (AB)5(CD)n]2(AB)5of one-dimensional photonic crystal(AB)m(CD)n(AB)m(CD)n(AB)m is calculated by means of the transfer matrix method including negative refraction materials.The phenomenon of splitting is analyzed.The results show that at the same cycle period the transmission spectra numbers of C and D media with either all the equal right-handed materials or left-handed materials are different.The right-handed materials have two double transmission peak more than left-handed materials.No matter that C and D media are either all the equal right-handed materials or left-handed materials,when n is an even number,transmission peaks have long distance each other.When n is an odd number,transmission peak number equals to the periodicity of n-1.The transmission index changes with the change in refraction index of C and D media.These features can be used for the design of multi-channel tunable filter and ultra-deuse wavelength division multiplexing.
