“…Layer B, with thickness d B (quarter wave condition), is fulfilled by the PS, and is characterized by a hydrostatic pressure dependent refractive index n B [19]. The Octonacci sequence is created by the recurrence relation [12]…”

“…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. This sequence has a geometric origin: the octagonal Ammann-Becker tiling is ruled by the Octonacci sequence.…”

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 the last few decades, 1D, 2D, and 3D photonic crystals (PCs) and phononic crystals have been received extensive attention in sensing applications as a biochemical sensor, salinity sensor, and filters (El-Khozondar et al 2019 ; Arafa et al 2017 ; Beheiry et al 2010 ; Natesan et al 2018 ; Arunkumar et al 2019 ; Amiri et al 2019 ; Elsayed and Mehaney 2018 ; Zaky et al 2020 ; Abd El-Ghany et al 2020 ; Zaky and Aly 2020 ; Khateib et al 2020 ).

There is a forbidden region for a specific range of wavelengths in a propagated electromagnetic wave.…”

The performance of one-dimensional photonic crystal for plasma cell application is studied theoretically. The geometry of the structure can detect the change in the refractive index of the plasma cells in a sample that infiltrated through the defect layer. We have obtained a variation on the resonant peak positions using the analyte defect layer with different refractive indices. The defect peak of the optimized structure is red-shifted from 2195 to 2322 nm when the refractive index of the defect layer changes from 1.3246 to 1.3634. This indicates a high sensitivity of the device (S = 3300 nm/RIU) as well as a high Q-factor (Q = 10 3 ). The proposed sensor has a great potential for biosensing applications and the detection of convalescent plasma.
