Variation of central frequency of all three the optical channels' in terms of Fermi energy for TE polarization state under normal incidence in a third-order F-1D PhC structure with \(N=4\). The central frequencies of all three optical channels shown in green, blue and magenta colors and ranges from \({(f}_{1}, {f}_{2}, {f}_{3})=(7.885, 8.114, 8.336)\)Â THz at \({E}_{F}=60\)Â meV to \({(f}_{1}, {f}_{2}, {f}_{3})=(9.13, 9.33, 9.538)\)Â THz at \({E}_{F}=80\)Â meV.
