摘要：

A novel integrated fiber-optic sensor based on a symmetrical twin-core fiber was proposed and demonstrated as a strain sensor. By heating and tapering the symmetrical twin-core fiber, the light from one core can be partly or completely coupled into the other core in the coupled zone as the twin-core fiber was pulling. By detecting the output power of any one core, the strain applied on the twin-core fiber can be detected. The output power of twin core fiber versus the applied strain was experimentally investigated, and the results showed that the twin-core fiber can be used as a strain sensor.
