Non-Hermitian CT-Symmetric Spectral Protection of Nonlinear Defect Modes

Do Hyeok Jeon, Mattis Reisner, Fabrice Mortessagne +2

We investigate, using a microwave platform consisting of a non-Hermitian Su-Schrieffer-Heeger array of coupled dielectric resonators, the interplay of a lossy nonlinearity and CT-s…
