Computing optical bandwidth of bandpass filter using metamaterial-based defected 1D PhC

Optical bandwidth of bandpass filter with metamaterial based defected one-dimensional photonic crystal is analytically computed. Two different metamaterial namely parallel nanorod and nano-fishnet with elliptical void are considered for the design of bandpass filter, and both normal and oblique incidences (with all types of polarization) are considered for analyzing performance. Defect density is considered within practical limit for making the simulated output of practical importance. Structural parameters are tuned within fabrication limit, and angle of incidence are also tuned within feasible limit for which bandwidth is determined. Theoretical findings have practical importance as filter with sub-micron bandwidth can be utilized in all-optical integrated circuit.Optical bandwidth of bandpass filter with metamaterial based defected one-dimensional photonic crystal is analytically computed.
