چکیده مقاله :
In this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. Currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twomechanisms such as (a) The resonant cavities and (b) Ring resonators. The applied mechanism inoptical filter used in this article is the resonant cavities. In this filter, filtering act is operated byusing cavity located between output Waveguide and input waveguide and it has been used todesign filter at the first extracted band structure and we have applied forbidden band photonicbased-crystal by using PWE method. Then, the calculations related to filter output spectrum werecarried out by using an FDTD method. Thus, the effect of cells' radius on the behavior ofwavelength switching optical filter has been investigated in this study.
