Abstract

In this work, the effect of the ratio of hole radius to lattice spacing (r/a₀) on transmission characteristics for the metal/dielectric photonic crystal (MDPC) is investigated. The relationship between the photonic band gap (PBG) dependent on r/a₀ is discussed. This is because the characteristics of the PBG dependent on r/a₀ affect transmission characteristics for MDPC. The plane wave method (PWM) is used to simulate the PBG by changing r/a₀ from 0.2 to 0.3. For hexagonal arrays, we find that with r/a₀ being 0.25, the desired PBG structure is achieved. The experimental study for hexagonal air holes arrays residing in the Au@SiO₂@Si structure by changing r/a₀ from 0.2 to 0.3 is presented. The result shows that with r/a₀ being 0.25, a narrow bandwidth and high efficiency transmission is achieved. It is demonstrated that the distinct effect of r/a₀ on transmission characteristics for MDPC structure.
