Figure 3: Simulation of photon transmission spectroscopy.
From: Quantum simulation of 2D topological physics in a 1D array of optical cavities
(a) Calculated transmission spectra 
of 
under different values of magnetic flux φ0. Since it is possible to measure the transmission coefficient between every pair of lattice sites, we add transmissions to all output channels to obtain a strong signal and increase the sensitivity of the measurement. (b) Calculated transmission spectrum 
of 
, where 
. In both a and b, the size of the simulator N=10. The OAM number of the photon included in the calculation is l∈[−50, 50]. Open and periodic boundary conditions are used in the x and y direction. The photon loss γ=0.1κ.
