- Abstract summary: We explore the photon transfer in the nonlinear parity-time-symmetry system of two coupled cavities.
We find that the saturated gain in the weak coupling regime does not match the loss in the steady state.
The photon transmission efficiency in the parity-time-symmetric regime is robust against the variation of the coupling strength.

- Abstract: We explore the photon transfer in the nonlinear parity-time-symmetry system
of two coupled cavities, which contains nonlinear gain and loss dependent on
the intracavity photons. Analytical solution to the steady state gives a
saturated gain, which satisfy the parity-time symmetry automatically. The
eigen-frequency self-adapts the nonlinear saturated gain to reach the maximum
efficiency in the steady state. We find that the saturated gain in the weak
coupling regime does not match the loss in the steady state, exhibiting an
appearance of a spontaneous symmetry-breaking. The photon transmission
efficiency in the parity-time-symmetric regime is robust against the variation
of the coupling strength, which improves the results of the conventional
methods by tuning the frequency or the coupling strength to maintain optimal
efficiency. Our scheme provides an experimental platform for realizing the
robust photon transfer in cavities with nonlinear parity-time symmetry.
