| Abstract | ||
| In this paper, the type of photonic crystals (PCs) which consists of air holes surrounded by silica as a background with square lattice arrangement in two dimension (2D) has been assumed. A plane wave expansion method (PWEM) is implemented to calculate the photonic band structure of this kind of PC, then the effect of changing air filling fraction is studied on the photonic band structure diagram, by changing the air hole radius and lattice constant (a). As a result, a tuning and shifting of the photonic bandgaps (PBGs) has been obtained. | ||
