| 摘 要： | We present a simple method to induce mechanically a long-period fibre grating in a general sing mode fibre.The transmission spectrum of the new type of grating can be tailored by changing the external applied pressure or by introducing a phase-shift in the grating.The tunability this kind of gratings exhibit will be particularly useful for the filter design.
