THz Bandpass Filter Design Using Metamaterial-Based Defected 1D …

5 Conclusion
Henceforth, all possible bandwidth variations are illustrated in this section for both
TE and TM mode of propagations, where 1550 nm is considered as the central
wavelength for the filter design. From the results, it can very easily be concluded
that THz bandwidth can be obtained for 1D PhC-based filter, where the nanometric
change in layer dimensions at the time of fabrication leads to the fluctuation in
bandwidth. Moreover, the change of incidence angle also changes the bandwidth.
Henceforth, simulation findings are extremely crucial for determining the optical
properties before making the photonic integrated circuits. Results also speak about the
range of incidence angle required for making the filter under operating condition, for
both TE and TM modes. A comparative study suggests that paired nanorod provides
a continuous monotonic increment of bandwidth with the change of incidence angle
for both the modes, which is not possible once nanofishnet structure is considered.
However, the nanofishnet structure provides a higher frequency of operation which
is beyond to 10
15 Hz. Hence, the compromization is required depending on the
application requirement.
