    "abstract": "We theoretically investigate the response of optical phase conjugators to\nincident probe pulses. In the stable (sub-threshold) operating regime of an\noptical phase conjugator it is possible to transmit probe pulses with a\nsuperluminally advanced peak, whereas conjugate reflection is always\nsubluminal. In the unstable (above-threshold) regime, superluminal response\noccurs both in reflection and in transmission, at times preceding the onset of\nexponential growth due to the instability.",
