(INVITED) Exceptional points of parity-time- and anti-parity-time-symmetric devices for refractive index and absorption-based sensing
Parity-time symmetry has gained attention in optical research, for the interesting properties of exceptional points of showing enhanced sensitivity to external perturbation. Such a property has been widely proposed for different applications. Recently, also anti-parity-time symmetry has gained a gro...
