Exceptional-point-enhanced sensitivity: A new paradigm for high-sensitivity fiber sensors

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 transform fiber sensing technology toward a new era of precision and accuracy. While the researchers demonstrated this remarkable capability using a bending sensor, the true power of EP-enhanced sensitivity extends far beyond, with potential applications across various existing fiber sensors.
