Abstract: A temperature-compensated refractive index (RI) sensor based on thinned strongly-coupled seven-core fiber (SC-SCF) supermode Bragg grating and interferometer is demonstrated. The SC-SCF ...

The moves came just before the annual U.N. General Assembly, increasing pressure on Israel and putting key allies at odds with the Trump administration. By Mark Landler Reporting from London Britain, ...

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 ...

Find out how the VX 120+ Dry Eye and Eye Refract, both from Visionix, have made a difference for one California practice — and how they can do it for your practice as well. Since adding the Visionix ...

In this work, a refractive index sensor structure is proposed, which consists of the met-al-insulator-metal (MIM) waveguide coupling with ring resonator with a rectangular cavity. Its sensing ...

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 ...
