Southampton optical circuit start-up Stratophase has developed a sensor that can measure the refractive index of liquids to better than one part in a million (1ppm). After the team got their prototype ...

Even miniaturized RI sensors can be too large for many applications to accommodate, but one research team is hoping to change that. Most engineers are familiar with the basic physical parameters which ...

Terahertz photonic crystal fiber sensors, powered by machine learning, could transform tuberculosis detection with rapid and ...
