| Figure 15. The experimental realization of a non-Hermitian lattice with asymmetrical hopping amplitudes based on coupled microresonators. Resonators An and Bn couple with each other via the microring with a half perimeter loss and gain. The photons in resonators An (Bn) hop into resonators Bn (An) through the paths marked with the black solid arrows and the black dashed arrows. |
