“…So far, QPPCs of several kinds have been investigated; among them are Fibonacci, Thue-Morse, Rudin-Shapiro, double periodic, octonacci, Cantor and Pell-like structures [4]. Earlier, deterministic PCs were successfully used for optical filtering, multi-frequency terahertz manipulation, near-perfect absorption and omnidirectional reflection, photoluminescence emission enhancement [5][6][7][8][9][10][11][12]. Fibonacci and Thue-Morse-like photonic structures have been reported for the Bloch-like surface waves [13] and multimode photon-exciton coupling [14], which represent a significant advantage compared to periodic PC counterparts.…”

We propose an elegant approach to produce photonic band gap structures with multiple photonic band gaps (PBGs) by constructing quasiperiodic photonic crystals (QPPCs) composed by a superposition of photonic lattices with different periods. Generally QPPC structures exhibit both aperiodicity and multiple PBGs due to their long-range order. They are described by a simple analytical expression instead of quasiperiodic tiling approaches based on substitution rules. Here we describe the optical properties of quasiperiodic photonic crystals exhibiting two PBGs that can be tuned independently. PBG interband spacing and their depths can be varied by choosing appropriate reciprocal lattice vectors and their amplitudes. These effects are confirmed by the proof-of-concept measurements made for the porous silicon based QPPC of the appropriate design.

In this study, we demonstrate two different methods to generate one-dimensional photonic crystals (PCs) based on aperiodic dielectric gratings and investigate their optical filtering characteristics. The first grating design approach relies on a function formed by the summation of two cosine functions that exhibit different spatial frequencies corresponding to predefined reciprocal lattice vectors (RLVs) and hence generating a grating function by placing the refractive index layer boundaries at the zero-crossing locations of this function. The second design approach starts with the discretization of the total grating thickness with layers of equal thicknesses and each layer’s refractive index is selected to maximize the magnitude of the Fourier transform of the grating function at the spatial frequency locations corresponding to predefined RLVs. The non-periodic dielectric multilayers are exposed to time domain calculations utilizing finite-difference time domain method. Using numerical calculations, transmission properties of the designs are investigated and the free adjustability of the photonic bandgap locations in the spectra is demonstrated for both methods. With these advantages, both methods prove to be practical solutions for the design of optical filters based on one-dimensional PCs utilizing aperiodic index modulation.
