The chikungunya virus (CHIKV), transmitted by mosquitos, induces severe symptoms such as joint pain, headaches, and exhaustion, necessitating swift diagnosis and intervention. In this investigation, the transfer matrix method is employed to enhance virus detection using a ternary photonic crystal (PC) biosensor across normal and infected blood constituents-plasma, platelets, red blood cells, and uric acid. These components possess distinctive refractive indices crucial for the biosensor's selective CHIKV detection. A peak sensitivity of 800 nm∕RIU at N ¼ 4 is achieved by analyzing PC transmittance spectrum curves in the presence of diverse blood elements to emulate real-world conditions. Optimal average sensitivity at 1037.5 nm∕RIU is observed at incidence angles of 30 deg, 55 deg, and 80 deg, with 30 deg yielding the highest quality factor of 1015.94. This PC-based biosensor exhibits promise for compact, highly sensitive, and precise virus detection, potentially advancing viral detection biosensor technology and enhancing diagnostic tools for infectious diseases.

“…PCFs leverage the bandgap mechanism, which provides a high damage threshold and low nonlinearity depending on the design. This allows for the exploration of fundamentally different physical mechanisms to manipulate light (Li, et al 2019;Gangwar, et al 2023). Modified total internal reflection (MTIR) and the concept of single-mode guidance across a wide spectral range are achievable in PCFs, offering operation across a broad spectrum of wavelengths (Li, et al 2022; Kiroriwal and Singal 2023).…”

The ability to transmit data at a high transmission rate is one of the main challenges that has limited the performance of visible light networking systems. In this paper, we present an eight-core photonic crystal fiber designed for multiplexing (MUX) operations at wavelengths of 1.32, 1.3, 1.54, 1.19, 1.4, 0.98, 1.35, and 1.1 µm to overcome this issue. Various MUX parameters, such as transmission rate and normalized power, are examined in this numerical study. A multiplexer is a device that enables multiple messages or signals to be conveyed simultaneously through a single communication channel. A specific type of optical fiber, called photonic crystal fiber (PCF), is used in this context, which has a cladding made of photonic crystals surrounding the fiber core. The fiber features a periodic arrangement of tiny air holes along its length, creating a low-loss periodic dielectric material known as a photonic crystal. In this new design, silica rods are employed instead of multiple air-hole zones along the fiber's length to adjust the coupling length between adjacent channels. The results indicate that after 5.5 mm of light propagation, the operating wavelengths can be effectively multiplexed.

“…The ability to incorporate special substances with a wide range of refractive index values is the primary advantage of building a mux device using a PCF design. This is because the bandgap [10,11] and modified total internal reflection (MTIR) [12,13] are the basis of light-guiding mechanisms in PCF. The ability to reduce coupling length is the other gain, particularly compared to tightly coupled ports (cores).…”

A brand-new four-channel mux system built entirely out of multicore photonic crystal fiber (PCF) structures, which permit wavelength multiplexing at 0.85, 1.19, 1.1, and 1.35 µm, has been confirmed. The multiplexer is a device that sends multiple messages or signals simultaneously via one communication channel. PCF is a category of optical fiber primarily according to the characteristics of photonic crystals, and it is an effective waveguide based on the interaction of microstructured materials with various refractive indices. Silica substance was used to fill up a few air-hole places to optimize the PCF mux structure along with coupling light between more nearby ports (cores) over the PCF axis. The low-index portions are air holes that may be found anywhere along the length of the fiber, and the background material is often natural silica.
