SENSING FIBER AND SENSING DEVICE

摘要

A sensing fiber adapted to transmit a sensing light along a path and sense an object is provided. The fiber includes a core, a plurality of photonic crystal structures surrounding the core, a sensing surface and a metal sensing layer. The core is located at the center of the fiber. The photonic crystal structures extend along the path. The sensing surface extends along part of the path and adjacent to the core, and the metal sensing layer having a plurality of metal grating structure is disposed on the sensing surface. When the fiber is sensing the object, the metal sensing layer is located between the sensing surface and the object, and part of the sensing light will be converted into a signal light by the object on the metal sensor layer. A sensing device is also provided.
