Abstract：
 A process based on single-mode transmitting optical fibre for preparing the optical fibre to implement different performance of acousto-optic filter includes using a commercially available optical fibre for transmission purpose, determining needed external diameter and etching speed, and etching the optical fibre by controlling etch time to change its refractivity in acousto-optical action region. Its advantages are simple process, easy control, high effect, no damage to core of optical fibre, and low loss of optical fibre.
