Paper Abstract

Transmission studies for quantum well (QW) structures composed by two-dimension photonic crystals are presented. The results indicate that, with the multiple QW structure, each resonant peak which appears in the single QW structure would split, and the splitting times increases in step with the increasing number of the wells. It is also found that the frequency spacing between adjacent splitting spectra can be finely tuned by adjusting the barrier widths properly, leading to great improvement of spectral efficiency. The physical explanation of the origin of the spectral splitting are provided. These results provide the prospects in super dense wavelength division multiplexing for optical communication and precise optical measurement for the purpose of maximization of channel density.
