8 February 2012A Brillouin gain based fast light fiber laser for sensing
applications
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.
