We present a novel superluminal fiber laser based super-sensor employing Brillouin gain. The white light cavity condition is attained by introducing an additional ring cavity into the main cavity. By adjusting the parameters of the laser cavity and those of the phase component it is possible to attain sensitivity enhancement of more than two orders of magnitude compared to conventional laser sensors. The tradeoffs between the attainable sensitivity enhancement, the cavity dimensions and the impact of the cavity roundtrip loss are studied in details providing a set of design rules for the optimization of the super-sensor.
