Abstract :
A semi-finished single mode multimode single mode fiber structure with an air gap is investigated and its displacement sensing characters are proposed. The distance between the MMF and the SMF used as a "receiver" can be detected by tracing the associated minimum position of waveform in spectrum. Good linearity is shown in the relationship between displacement and wavelength.
