| Research Abstract |
We have studied a super-high sensitivity fiber sensor by a new detection technique. A metallic thin film or metal nanoparticles have formed on the surface of silica fiber used for optical communication system. The free electrons of the metal surface are excited by the electric field of transmitting light, and then collective oscillation of electrons, called surface plasmon resonance occurs. This induces the phase shift of light. This shift has been detected using a multimode interference produced by the special fiber configuration. We clarified that the resonance wavelength of the light can be controlled by changing the metal structure.
