Abstract

The impact of material dispersion in the performance of parity-time (PT) symmetric coupled microresonators is studied. The eigenfrequencies of the coupled PT-system are analysed for different dispersion parameter. We show that realistic dispersion preserves the PT-system with additional stabilising features.
