Fig. 1: Schematic of the 11-RWA and principle of programming Hamiltonian.
From: Programmable high-dimensional Hamiltonian in a photonic waveguide array
a The RWA has 11 waveguides (black) and 22 electrodes (orange) across the coupled region. The electrodes are controlled by multi-channel arbitrary waveform generators (Supplementary Fig. 1). b Cross-section of the 11-RWA device. The black regions indicate the mode shapes of the annealed proton-exchange waveguides. c The Hamiltonian parameters can be individually controlled with high precision.
