Search for: [Abstrakt = "Motivated by the analogy between a phaseconjugating mirror \(PCM\) and a superconductor, we search for optical counterparts of the well\-known DC and AC Josephson effects. We show that in a system consisting of two PCM’s separated by vacuum an „optical supercurrent” arises as a function of an applied phase difference between the PCM’s, which is the optical analogue of the DC supercurrent flowing in a superconducting weak link. The corresponding AC effect occurs when the two PCM’s are pumped by light of a different frequency, causing the phase difference to oscillate in time with the frequency difference."]
