Convergence analyses of the simulation. With a soft sink to eliminate the outgoing light component, the impinging light profile reconstructed from back-propagated light is compared to the original outgoing light in the forward scenario. The accuracy of the simulation increases with: (a) increased number of simulation time-steps (CW steady state), and, (b) increased distance between the OPC region and the scattering medium, where outgoing light impinges the OPC region at near normal incidence.
