“…In the limit of infinite systems, the transmission bands form a Cantor set with Lebesgue measure zero, and it is assumed that either only complete transmission or complete reflectance occurs [9,10]. However, for physical applications usually systems with relatively small numbers of layers are used [4,6]. In Figure 3, the results for the transmission coefficients T(#, !)…”

“…In this context, quasicrystals, which are regarded as having a degree of order intermediate between crystals and disordered systems, are of special interest because they often possess unexpected physical properties due to their complex symmetries [1][2][3]. This qualifies them for the potential application in several optical devices such as single-mode light-emitting diodes, polarization switches, and optical filters [4][5][6]. An interesting application is also the construction of microelectronic devices that are based on photons rather than on electrons, so that they potentially can be the electromagnetic analogue of semiconductors [7,8].…”

The propagation of s-and p-polarized light through quasiperiodic multilayers, consisting of layers with different refractive indices, is studied by the transfer matrix method. In particular, we focus on the transmission coefficients of the systems and their dependence on the incidence angle and on the ratio of the refractive indices. We obtain additional bands with almost complete transmission in quasiperiodic systems at frequencies in the range of the photonic band-gap of a system with a periodic alignment of the two materials for both types of light polarization. With increasing incidence angle these bands bend towards higher frequencies, where the curvature of the transmission bands in the quasiperiodic stack depends on the metallic mean of the construction rule. Additionally, in the quasiperiodic systems for p-polarized light the bands show almost complete transmission near Brewster's angle, in contrast to the results for s-polarized light. Further, we present results for the influence of the refractive indices at the mid-gap frequency of the periodic stack, where the quasiperiodicity was found to be most effective.

[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] Quasiperiodic systems possess properties which are intermediate between those of periodic systems and random systems. As is well-known, band gaps appear in the density of states of periodic systems and affect many of their physical properties.…”

We explore the interplay between surface plasmon excitations and quasiperiodicity theoretically by studying the optical properties of multilayer structures made of thin metal and dielectric layers and constructed using the Fibonacci quasiperiodic sequence. Using the invariant imbedding theory of wave propagation, we calculate the reflectance, transmittance and absorptance of p-polarized electromagnetic waves incident obliquely on Fibonacci metal-dielectric multilayers in the Otto configuration. We find that due to the excitation of surface plasmons, there appear several angles above the critical angle at which the reflectance takes local minima and the transmittance and the absorptance take local maxima. We observe that there are parameter regions where either transmission or absorption is anomalously large. As the generation number of the Fibonacci sequence increases, the curves converge to characteristic limiting curves. We find a surprising behavior that in some parameter region, the wave is completely absorbed by the Fibonacci structure. We examine this phenomenon by calculating the magnetic field distribution inside the Fibonacci structure.

“…In previous studies, the optical properties of quasi-periodic QWs have been investigated and have been compared with those of periodic ones [22][23][24][25]. In particular, in terms of light emission, the results have shown that the PL intensity in a Fibonacci quantum well (FQW) is significantly stronger than that in a PQW, not only under the Bragg condition, but also under the anti-Bragg condition [23,26]. It has also been found that the properties of PL intensity in a Thue-Morse quantum well (TMQW) are similar to those in a PQW [5].…”

Twin extra-high photoluminescence in resonant double-period quantum wells

2014

View full text Add to dashboard Cite

Twin extra high photoluminescence (PL) in resonant quasi-periodic double-period quantum wells (DPQWs) for higher-generation orders is demonstrated. In the DPQW, the number of maxima in the maximum values of the PL intensity is two, which is different from other quasi-periodic quantum wells (QWs) and traditional periodic QWs. The maximum PL intensity in a DPQW is also stronger than that in a periodic QW under the anti-Bragg condition and that in a Fibonacci QW. Although the peaks of the squared electric field for the twin PL are both located near the QWs, their field profiles are distinct.
