Abstract
We present a numerical study of optical properties of an
octagonal quasi-periodic lattice of dielectric rods. We report on a complete
photonic bandgap in TM polarization up to extremely low dielectric
constants of rods. The first photonic bandgap remains open down to
dielectric constant as small as ε = 1.6 (n = 1.26). The properties of an optical
microcavity and waveguides are examined for the system of rods with
dielectric constant ε = 5.0 (n = 2.24) in order to design an add-drop filter.
Proposed add-drop filter is numerically characterized and further optimized
for efficient operation. The two-dimensional finite difference time domain
method was exploited for numerical calculations. We provide a numerical
evidence of effective add-drop filter based on low index material, thus
opening further opportunities for application of low refractive index
materials in photonic bandgap optics.
