We present 3-D FDTD simulation results to specify the relevant parameters of photonic bandgap (PBG) structures in asymmetric strip waveguide. These mandatory simulations act as pre-processing step before CMOS fabricating of a one-dimensional photonic crystal (PhC) Fabry-Perot filters on a Silicon-on-Insulator (SOI) wafer. The microcavity filters were formed by holes inside of the stripe waveguide. Tuning the Fabry-Perot filter parameters (holes diameter, holes number and cavity length) which make effects on the transmission characteristics (center wavelength, spectral bandwidth, maximum transmission) were investigated. Influence of first and higher order cavity length as well as the number of cavities on the filter spectral shape was analyzed. Finally, in order to achieve the desired spectral shape of the filter function for several applications, a number of different cavities were designed and investigated. Simulation spectral results of the designed filters will be compared to the measurement results.
