Scientists have recently discovered a new way of enhancing the sensitivity of a fiber optic system. Known as the “exceptional point enhanced sensitivity paradigm,” this method has the potential to allow fiber optic systems to achieve a record-breaking level of sensitivity. The EPESP utilizes the principles of two coupled waveguides and the phenomenon of exceptional points to create a unique system in which light is transferred between the two waveguides with extraordinary precision. This high level of sensitivity opens up the possibility of further advancements in the field of fiber optics, which could lead to a revolution in the way we use and interact with optical technology.
