Nonlinear parity-time symmetric closed-form optical quadrimer waveguides: attractor perspective
No full textWe report a study on a closed-form nonlinear parity-time symmetric optical
quadrimer waveguides system with a specific coupling scheme. The system yields
power saturation behavior in the modes, which may be attributed to the inherent
attractor in the system. A detailed analysis has been provided to confirm the
attractor aspect of the system. This work also addresses a crucial issue
regarding choice of initial conditions while carrying out numerical simulation
for such systems
