Design of polarization splitter based on dual-core surface plasmon resonance photonic crystal fiber

Dual-Core Photonic Crystal Fiber Polarization Beam Splitter Based on a Nematic Liquid Crystal with an Ultra-Short Length and Ultra-Wide Bandwidth

“…Table 2 presents a comparison of the simulation results between the proposed PS-DC-PCF PBS and other reported DC-PCF PBSs. By observing Table 2, it is noted that the maximum ER values in references [12,14,[35][36][37] are all higher than those within this study. However, it is worth noting that the operational bandwidth of PCF PBS refers to the wavelength range where ER is greater than 20 dB, while in some studies, the operational bandwidth may only exceed 10 dB [12,38] or 15 dB [36].…”

“…Hence, the crucial aspect lies in comparing the lengths of the splitters and the widths of the operational bandwidth. A further examination of the results in Table 2 reveals that most DC-PDF PBSs [13,[35][36][37][38][39][40][41] neither possess the operational bandwidth proposed in this paper nor do they have shorter splitter lengths than the one in this study. It is important to note that the DC-PCF PBS structures proposed in references [35,36,38,41] include elliptical holes, indicating an increase in manufacturing complexity.…”

Furthermore, this s include elliptical holes but adopts only circular holes, thus reducing manu and structural manufacturing complexity.…”

“…It can be observed from Figure 16 Table 2 presents a comparison of the simulation results between the DC-PCF PBS and other reported DC-PCF PBSs. By observing Table 2, it is maximum ER values in references [12,14,[35][36][37] are all higher than those wit However, it is worth noting that the operational bandwidth of PCF PBS refe length range where ER is greater than 20 dB, while in some studies, the ope width may only exceed 10 dB [12,38] or 15 dB [36]. Therefore, even if the value at a certain wavelength is high, the final spectral bandwidth may not the widest.…”

Advances and challenges in conventional and modern techniques for halal food authentication: A review

“…Surface plasmon resonance technology is a robust technique utilized in the certification of halal food. The operational mechanism of this system is based on the detection of alterations in refractive index occurring on a sensor surface because of the interaction between polarized light and a thin metal film, commonly composed of gold (Revathi & Rajeswari, 2022 ). In case of halal verification, the employment of SPR can be employed to discern and identify chemicals that hold significant importance in adhering to Islamic dietary regulations.…”
