Query: Scalable higher-order exceptional surface with passive resonators   The sensitivity of perturbation sensing can be effectively enhanced with
higher-order exceptional points due to the nonlinear response to frequency
splitting. However, the experimental implementation is challenging since all
the parameters need to be precisely prepared. The emergence of exceptional
surface (ES) improves the robustness of the system to the external environment,
while maintaining the same sensitivity. Here, we propose the first scalable
protocol for realizing photonic high-order exceptional surface with passive
resonators. By adding one or more additional passive resonators in the
low-order ES photonic system, the 3- or arbitrary N-order ES is constructed and
proved to be easily realized in experiment. We show that the sensitivity is
enhanced and experimental demonstration is more resilent against the
fabrication errors. The additional phase-modulation effect is also
investigated.
