Slow–fast nonlinear dynamics and non-normal relaxation pulses near exceptional points in an autonomous Kerr dimer

We study an active–passive Kerr dimer in which a slow saturable reservoir and unequal Kerr shifts make the optical state drive its own non-Hermitian spectral trajectory. Direct integration shows stable narrow relaxation pulses with T = 248.077 and I max = 24.604 , preceded by fin...
