Abstract

We present experimental evidence of a 64th order exceptional point realized on a time-multiplexed photonic resonator network. Our highly scalable implementation uses a unidirectionally coupled one-dimensional lattice to achieve higher order exceptional points that are robust to variation in nearest neighbor couplings. Moreover, the non-reciprocal couplings of our network allow for the possibility to exceed the signal to noise limits that restrict other exceptional point implementations.
