(a) Energy band diagram of the GPC for different μc1. k is the Bloch vector of the GP modes and D is the period of the GPC. (b–d) Energy band diagrams with μc1 equal to 0.4, 0.5 and 0.6 eV, respectively. The gray regions illustrate the forbidden bands of the GPCs. In the calculations, r is assumed as 1.25.
