A tunable wide bandgap can be achieved by introducing the defects into the stubs and a larger bandgap width about 1.35 times compared to its counterpart without defects is acquired. It is found that both the defects and number of periods play the crucial roles to affect the bandgap performance, which is attributed to the change of effective refractive index and plasmon resonance modes in the proposed structure. The proposed plasmonic filter has potential to be a promising alternative structure to realize in integrated optical circuits for optical trapping and tunable devices. |
