GURYEV, I. et al. Analysis of integrated optics elements based on photonic crystals. Rev. mex. fis. [online]. 2006, vol.52, n.5, pp.453-458. ISSN 0035-001X.

We present the design of a demultiplexer based on photonic crystals (PC). The control of the refractive index, periodicity, geometry and size of the structure, are very important to light propagation in PC. The demultiplexer is intended to separate pulse channels with 1.3 and 1.55 µm wavelength into wide pass band wavelength division multiplexing (WDM) optical telecommunications systems. The dependence of the band gap width on the refractive index Δn between background and road lays is shown. The results of FDTD numerical simulation of wavelength channel splitting and the spectral analysis for the maximum efficacy of transfer energy are also presented.
