    "abstract": "We theoretically analyze wave packet transmission through a phase-conjugating\nmirror and show that the transmission of a suitably chosen input pulse is\nsuperluminal, i.e. the peak of the pulse emerges from the mirror before the\ntime it takes to travel the same distance in vacuum. This pulse reshaping\neffect can be attributed directly to the dispersion relation in the nonlinear\nmedium constituting the mirror. Thus, for the first time a connection is laid\nbetween optical phase conjugation and superluminal behavior. In view of its\nadditional amplifying ability, a phase-conjugating mirror is a most promising\ncandidate for an experimental observation of tachyonic signatures.",
