“…[7] These tiny, intense spikes might well be doubly adjustable in the envisioned Bragg periodic scattering by adjusting the striking angle of the EM wave or adding a voltage to the piezoelectric defect layer. This tunable characteristic is required for demultiplexers [8], a double tunable inline optical filter [9], and other applications. These fibers [1] are likewise nature-inspired structures that operate well when created in the visible to near-infrared wavelength range.…”

The propagation of H-polarized electromagnetic (EM) waves in polymeric (PEI)-chalcogenide (As2Se3) photonic materials (PCCPM) has been theoretically optimized and investigated in the current work. We used the Transfer Matrix Technique (TMT) and Hankel Realism (HR) in columnar coordinates to show numerical findings for the unit columnar junction and columnar slab for both polymeric (low refractive index) and chalcogenide (high refractive index) materials composed at least loss wavelength window (632.8 nm). The optical transmittance with wavelength for both materials for the cylindrical unitary slab displays oscillating and non-oscillating signatures, indicating that the starting radius has a significant impact on the transmittance at a constant slab width. The oscillatory transmittance becomes squizzing when the starting radius is increased. Furthermore, for smaller modal numbers, optical transmittance is an oscillatory function of slab thickness, and for (m=4), it becomes minimum and flat. These scientific breakthroughs pave the door for a variety of photonic devices and sensor applications.

A dynamically tunable metal clad planar waveguide having 0.62PMN‐0.38PT material is simulated and optimized for detection of cancer cells. Angular interrogation of the TE0 mode of waveguide shows that critical angle increases greater than the resonance angle with increasing of cover refractive index, which limits the detection range of waveguide. To overcome this limitation, proposed waveguide applies a potential on the PMN‐PT adlayer. Although a sensitivity of 105.42 degree/RIU was achieved at 70 Volts in testing the proposed waveguide, it was found that the optimal performance parameters were obtained at 60 Volts. At this voltage, the waveguide demonstrated detection range 1.3330–1.5030, a detection accuracy 2393.33, and a figure of merit 2243.59 RIU−1, which enabled the detection of the entire range of the targeted cancer cells. Therefore, it is recommended to apply a potential of 60 Volts to achieve the best performance from the proposed waveguide.

“…A band of wavelengths known as the PBG range is not permitted to pass through the HCBF structure. HCBF has many encouraging applications in doubly tuned multi-wavelength LASER sources [26] , biosensors [27] , tunable voltage multiplexers [28] , wavelength and intensity modulation [29] , [30] , etc. In this paper, the high RI contrast (e.g., chalcogenide glass Arsenic tri-selenide

and polymer film Poly-ether imide PEI) and multi-clad HCBF structure has been investigated.…”
