Abstract: The paper proposes an S-shaped fiber Surface Plasmon Resonance (SPR) sensor structure capable of simultaneously measuring refractive index (RI) and temperature for the first time. The ...

Abstract: A terahertz refractive index sensor, which relies on utilizing the Tamm plasmon polariton and localized topological edge state (TES), is proposed in a 1-D photonic crystal (PC) based on ...

Abstract: Visuotactile sensors have significant advantages in high-resolution contact shape sensing, which is crucial for robots to locate and manipulate objects. However, high precision and robust ...

The Brix scale, derived from the refractive index of a solution at 20 degrees Celsius (68 Fahrenheit), is widely known. Originally, it was established by determining the weight percentage of sucrose ...

Abstract: Current metalenses with large numerical apertures suffer from low efficiency. In this paper, we demonstrate a refractive-meta hybrid system consisting of a ball lens mainly providing the ray ...

Abstract: Optical fiber technology, prized for its lightness, compact nature, resistance to electromagnetic interference (EMI), and corrosion resistance, has been compelling and widely adopted, ...

Abstract: In this article, a temperature and refractive index sensing probe based on a photonic crystal fiber (PCF) with a silver film coating is proposed. We suggested a simple method for coating ...

Abstract: A star tracker operating inside the atmosphere requires stellar atmospheric refraction (SAR) correction with rapidness, autonomy, and accuracy to promote its attitude determination. To meet ...

Abstract: An approach to optimize the sensitivity and the limit of detection of on-chip refractive index sensor is proposed and demonstrated based on sub-wavelength grating racetrack microring ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...
