Effects of changes in the cavity resonator photonic crystal filters with nano cells
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 9
Abstract
Recently, regarding the performance of photonic crystal band-pass filters in optical networks connection, optical integrated circuits, and short wavelength with high frequency, has attracted a lot of attention. In this paper, Our goal is designing a new type of photonic crystal band-pass filters using a waveguide cavity in the form of reduction in size of the cell, that as a result we create a filter in the function of the urban wavelength with an acceptable bandwidth. Here, filters have been used and optimized that the operation has been conducted by Rsoft software and FDTD two-dimensional technique. The first is the reduction of the size of cells in waveguide and elimination of some cells in the same direction. The efficiency has increased more than the previous structures, it is about 80%.
