Resumen
Along the last years, much debate has been done on the efficiency of slow-light phenomena in order to enhance lightmatter interactions, especially for sensing purposes. This improvement could be key to develop more compact and sensitive devices. In this work we develop an all-fiber submicrometric displacement sensor using slow-light sensitivity enhancement in a lossy ring resonator. In the propos ...

Along the last years, much debate has been done on the efficiency of slow-light phenomena in order to enhance lightmatter interactions, especially for sensing purposes. This improvement could be key to develop more compact and sensitive devices. In this work we develop an all-fiber submicrometric displacement sensor using slow-light sensitivity enhancement in a lossy ring resonator. In the proposed structure the losses produced by the displacement of a mechanic transducer can be translated into strong variations of group index and therefore strong transmittance variations. We show that this effect is strictly related to slow light, and not related to confinement effects or any other. [--]
