Parity-Time coupled microresonators: Kramers-Kronig limitation
Conference Proceeding
Phang, S., Vukovic, A., Creagh, S. C., Sewell, P., Gradoni, G., & Benson, T. M. Parity-Time coupled microresonators: Kramers-Kronig limitation.
In this talk, we use a KKE argument to show that the presence of dispersion alters the eigen-frequencies of coupled PT coupled microresonators, so that their eigen-frequencies are no longer complex conjugates after the EP.
