“…It is worth noting that, in this system, practically the entire range of filling fractions can be achieved technologically. The advantages of the gap map approach have been demonstrated in our previous studies, looking at the design of a variety of one-dimensional (1D) PCs, including disordered [17], composite [18], omnidirectional [19], threecomponent [20] and resonator [21] structures.…”

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.

“…The first 1D "Si-air" photonic crystal selected had 6 periods, a lattice constant of a = 4 µm and a sufficiently large filling fraction, f Si = 0.6, to minimize any possible impact of thickness inhomogeneities in the Si walls [17]. Fig.…”

Abstract-In this work, we show that light intensity modulation can be realized in the system of one-dimensional time-variant photonic crystals. Different from conventional light modulators, the functioning of the proposed structure emphasizes on its spatial/temporal structures instead of inherent material properties. Additionally, our system can perform inherent light modulation without introducing external stimuli, thus avoiding direct contacts with electrodes (or other modulation sources), which would be preferable in certain environments. The influences of parameters such as light frequency, structure dimensions, and refractive index contrasts on the modulation performance of the time-variant photonic crystal were investigated by numerical simulations. The results provide a new strategy for light modulation, which may add functionalities in optical communication, integrated-optics or display technologies.

“…Our analysis is made by the transmittance which can be calculated by making use of the transfer matrix method (TMM) [22]. The TMM has been widely used in the analysis of electromagnetic wave properties in 1D PCs [23][24][25][26][27]. We shall show how the transmission peak (channel wavelength) will be shifted by the variation of doping density, the defect thickness, and the angle of incidence for both TE and TM waves.…”

Abstract-In this work, near infrared filtering properties in a transmission narrowband filter are theoretically investigated. The filter is a defective photonic crystal of (LH) N D(HL) N , where N is the stack number, L is SiO 2 , H is InP, and defect layer D is an extrinsic semiconductor of n-type silicon (n-Si). It is found that there are multiple transmission peaks within the photonic band gap (PBG) as the defect thickness increases. The filtering position can be changed by varying the doping density in n-Si. That is, the peak (channel) wavelength is blued-shifted when the doping density increases. In the angle-dependent filtering property, the channel wavelength is also blued-shifted as the angle of incidence increases for both TE and TM waves. These filtering properties are of technical use in the applications of semiconductor optoelectronics.
