Abstract:
The phenomenon of Optical Phase Conjugation (OPC) can be rigorously simulated using the pseudospectral time-domain (PSTD) technique. However, with finite computational memory, it is infeasible to simulate light propagating long optical paths. We report a robust OPC simulation technique that can account for long optical path lengths by sequentially inverting the electromagnetic fields. Specifically, the ideal efficiency of OPC refocusing of light through scattering medium can be accurately determined.
