“…Besides, the similar functionalities as periodic counterparts, such as PBG, negative refraction, the transmission properties of electromagnetic waves (EM) waves in PQC give some extraordinary results [6] like their branching band structures [7]. The more widely studied PQC are the Fibonacci [8,9], Thue-Morse [8], Cantor [10], Doubleperiod [8] and Rudin Shapiro [11]. However, research in Octonacci PQC [12] has been so far mainly limited to theoretical investigations of multilayered structures.…”

Here we would like to discuss the light transmission modulation by the one-dimensional polymeric quasi-multilayer which is formed according to substitutional generalized Octonacci with PMMA and PS as the constituent materials. In particular, we will present some theoretical findings using the well-known transfer matrix method. PBG inter-band spacing and depth can be managed by choosing the appropriate generation number. The number of PBGs is the same while increasing in the generation number and are shifted symmetrically towards the designed frequency. It also reveals the aroused forbidden frequency band can be manipulated by changing the applied hydrostatic pressure and the thickness of the constituent polymeric materials. The increase in pressure shows a blue shift in the PBGs while the increase in thickness of the polymeric material provides a redshift to PBGs. The proposed structure could be another possible system for optical device design specially multi-band tunable optical reflectors.

“…In this paper the channel information is obtained without any loss of bandwidth efficiency while ensuring illumination quality by reducing the flickering effect of an OFDM based VLC system. A 6.4% low frequency flicker is proposed in (Ali, Zhang et al 2016, Gao, Li et al 2017, the light output of LED drivers varies significantly at the double-line-frequency, which not only is considered as a harmful optical flicker, but also greatly affects the effectiveness of data transmission. An OFDM based VLC system with reduced flickering effects is investigated in (Kim and Jung 2015), the results show that the proposed method provides a 6.4% gain in bandwidth efficiency with a 4% reduction in flicker compared to a conventional OFDM-based method.…”

This paper focuses to analyze the data rate, bit error rate (BER), flickering & bandwidth of visible light communication (VLC) system. The existing modulation scheme ON-OFF Keying (OOK) is modified and produces the trade-off between these parameters. The modified ON-OFF Keying (MOOK) is proposed in which the variation in the transmitted pulses is investigated. Therefore, the square and rectangular pulses are used to transmit zero and one bits respectively. The duty cycle of square pulse is increased to improve the flickering performance. Moreover, it utilized the bandwidth and deteriorates the BER performance. The differential MOOK (DMOOK) modulation scheme is also proposed in which the ON period of square pulse (zero bits) is removed. Therefore, the data rate of DMOOK is increased because the duration of zero bit pulse is decreased. Similarly, the high bandwidth is utilized and BER performance deteriorates. All performance parameters are evaluated on Arduino based hardware VLC system. We conclude that the BER performance deteriorates by improving flickering performance and data rate of the VLC system.
