In this paper, we have presented a design and simulation of a graphene-coated surface plasmon resonance (SPR) based biosensor for targeting specific biological components. We have explicitly shown the detection of the hemoglobin level in blood samples and the glucose concentration level in urine sam...

This paper presents a twin-core photonic crystal fiber (TC-PCF) for early detection of blood cancer based on refractive index (RI) of the normal and cancerous blood cell. The samples of the normal and cancerous cells are considered at 30–70% and 80% in liquid form, respectively, and proposed to be i...

RIU and maintains excellent full width at half maximum (FWHM) characteristics, resulting in a very high figure of merit (FOM) of 2600, indicating superior performance. These promising results suggest that the optimized bowtie-shaped PCF biosensor can be effectively applied to detect a wide range of ...

In this paper, we numerically debrief an ultra-high sensitive surface plasmon resonance (SPR) biosensor utilizing thin layers of graphene oxide (GO) that have not been addressed adequately till now. By the deposition of GO on top of the metal-dielectric heterostructure, our proposed sensor can achie...

A novel polarization-maintaining and polarization-filtering negative curvature hollow core (NC-HC) fiber in the THz regime is proposed in this paper. Two different transmission bandwidths of 0.42 THz and 0.21 THz with losses lower than 9 dB/m are attained for y- and x-polarization, respectively. The...

Whispering gallery modes (WGM) have revolutionized the field of optical sensors. This paper presents a design and simulation of a novel structure called a “multi-core whispering gallery mode (WGM)” based on multiple evanescent waves coupling for detecting cancer cells and diabetes tear cells. This w...

Abstract In a photonic crystal (PC) array, a line defect (removal of a periodic structure) and position up-chirping (gradually decreasing lattice constant) are familiar terms to introduce light confinement and propagation due to the photonic bandgap (PBG). In this paper, we have proposed a new model...

In this paper, a high dispersion compensating photonic crystal fiber (PCF) has been proposed, fabricable with simple fabrication schemes. The lattice design structure is comprised of five rings of circular air-holes. The rings are arranged with an octagonal geometry. The fiber exhibits an ultra-high...

We present a modern dual‐channel surface plasmon resonance (SPR) biosensor that combines advanced photonic crystal fiber (PCF) design with machine learning (ML) techniques to achieve high sensitivity and accurate prediction. The proposed sensor performs very well over a wide refractive index range o...

Abstract In this paper, a single ring hollow-core anti-resonant fiber (HC-ARF) with five elliptical nested tubes and a silicon layer is presented and investigated. The geometrically optimized HC-ARF, proposed here, exhibits highest birefringence of 2.95×10 − 4 at 1550 nm by maintaining a birefringen...
