The sensitivity of a fiber sensor can be enhanced severalfold using an exceptional point (EP), according to a recent paper published in Opto-Electronic Advances. The technique has the potential to ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

In the pursuit of clean and renewable energy, hydrogen plays an important role. But a major challenge facing this transition is that the gas is explosive when mixed with air. For this reason, it is ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.230019 discusses exceptional-point-enhanced sensitivity – a new paradigm for high-sensitivity fiber sensors. The sensitivity of a ...
