Abstract
We report on a simple, highly sensitive interferometric vibration sensor that operates in reflection mode, which is suitable to monitor low frequencies with low amplitudes. The sensor was fabricated with a short segment of three strongly coupled core optical fiber. The device was protected with capillary tubes and it was placed in cantilever position. The sensor exploits the ultrahigh sensitivity of supermodes to small bending.
