Journal ArticleDOI
Exceptional points enhance sensing in an optical microcavity
TL;DR: An alternative sensing scheme is demonstrated, by which the sensitivity of microcavities can be enhanced when operated at non-Hermitian spectral degeneracies known as exceptional points, paves the way for sensors with unprecedented sensitivity.
Journal ArticleDOI
Enhancing the Sensitivity of Frequency and Energy Splitting Detection by Using Exceptional Points: Application to Microcavity Sensors for Single-Particle Detection
TL;DR: So-called exceptional points, degenerate quantum states, allow higher energy splitting under the same perturbation conditions, greatly improving the detection sensitivity of sensors as mentioned in this paper, and thus improving the performance of sensors.

Chiral modes and directional lasing at exceptional points.
Bo Peng,Sahin Kaya Ozdemir,Matthias Liertzer,Weijian Chen,Johannes Kramer,Huzeyfe Yilmaz,Jan Wiersig,Stefan Rotter,Lan Yang +8 more
TL;DR: It is shown how to impose a strong chirality and a switchable direction of light propagation in an optical system by steering it to an exceptional point (EP)—a degeneracy universally occurring in all open physical systems when two eigenvalues and the corresponding eigenstates coalesce.
Journal ArticleDOI
Sensors operating at exceptional points: General theory
TL;DR: In this paper, a general theory of sensors based on the detection of splittings of resonant frequencies or energy levels operating at so-called exceptional points is presented, where the complex-square-root topology near such non-Hermitian degeneracies has a great potential for enhanced sensitivity.
