“…However, a PBS in a PC will become the so-called complex PBS (CPBS) when the material losses are taken into account. A CPBS means that both the real and the imaginary parts of the Bloch wave vector can exist in the pass band or the stop band [10]. For related studies on the effects of losses on the wave properties, we mention the works of Ilič et al [11] and Beličev et al [12].…”

In this study, we theoretically investigate the near-infrared (NIR) photonic band structure (PBS) in a one-dimensional semiconductor metamaterial (MM) photonic crystal (PC). The considered PC is (AB)^N, where N is the stack number, A is a dielectric, and B is a semiconductor MM composed of Al-doped ZnO and ZnO. It is found that the photonic band gaps (PBGs) can be tunable by the variations in filling factor, and thicknesses of A and B. It is of particular interest to see that the PBG will vanish when the thicknesses of A and B satisfy a certain condition. The results provide fundamental information on a NIR PBS that could be of technical use in photonic applications using such a semiconductor MM. The band gap vanishing makes it possible to design a wider band pass filter at NIR based on the use of such a PC.

“…This study of the impact of the effect of focus should enable an improvement of the optical quality of PCs obtained by microstructuring of silicon. The results are applicable across a wide wavelength range, from the visible to far-infrared, and assist in the engineering of Si based photonic elements for use in optical communication, integrated-optics and display technologies [22][23][24][25][26].…”

Abstract-The influence of beam convergence on the photonic bandgaps, or stop-bands (SBs), of one-dimensional photonic crystals (1D PCs) is investigated. The investigation is based on an analysis of the gap map obtained from reflection spectra, calculated by the transfer matrix method for various angles of light incidence, ϕ, and polarisations. The calculated data is compared with reflection spectra taken using Fourier Transform Infrared microspectroscopy. It was found that the introduction of the parameter, ∆ϕ to account for the focused light beam, for angles up to 20 • , has little effect on the first, or lowest SB and the SBs adjacent to it. However, an increase in the order of the SB causes an increase in the influence of this parameter.

“…This can be done by an external agent such as electric or magnetic fields by using the electro or magnetooptical effects of the materials with changing the electric permittivity's or magnet permeability's, respectively. [14][15][16][17] In pervious proposed PPC structures, the properties of the optical spectrum has been investigated by changing the PC parameters (such as defect layer thickness or refractive index 5 ) or plasma parameters (such as density of electrons, plasma frequency, or damping 10 ). In this paper, we have proposed a one dimensional PPC structure with arrangement of (AP) n D(PA) n , where A and B are dielectric layers and P stands for externally magnetized plasma layers.…”

A one dimensional plasma photonic crystal (1DPPC) structure was proposed to design a tunable compressing/broadening multi-channel optical filter with external controllability. The 1DPPC with arrangement of (AP) n D(PA) n , where A and D are the dielectric materials, P is a magnetized plasma layer and n is the number of the periodicity, was proposed. The well-known transfer matrix method was employed for analysis. In linear transmittance spectrum, n À 1 defect modes were appeared inside the photonic band gap. The results were shown that by increasing the applied magnetic field intensity and its direction, a red-shift and blue-shift were, respectively, observed in defect mode frequencies. On the other hand, the modes were compressed and broadened with increasing the intensity and the direction of the applied magnetic field, respectively. Externally controllable defect modes can be useful in designing a multichannel tunable optical filter. V C 2015 AIP Publishing LLC.
