#High-order synthetic dimensions in waveguide photonic lattices
“#High-order synthetic dimensions in waveguide photonic lattices” (a) Scheme of a four-waveguide array excited by a coherent state α〉 (red arrow indicates the excited waveguide). (b) Synthetic graphs emerging from the coherent state excitation of the system in (a). Since we are exciting with a coherent state, the probability amplitudes for each event are given…
