Dependence of central frequency of all three optical channels on the incident angle for TE polarization state at fixed values of \({E}_{F}=80\)Â meV and \(N=4\) in third-order F-1D PhC. The central frequencies of all three optical channels shown in green, blue and magenta colors and changes from \({(f}_{1}, {f}_{2}, {f}_{3})=(9.13, 9.337, 9.53)\)Â THz at \(\theta =0\) to \({(f}_{1}, {f}_{2}, {f}_{3})=(9.282, 9.479, 9.67)\)Â THz at \(\theta ={80}^{^\circ }\).
