    Abstract

    Properties of fanning effect and two wave coupling in a Ce∶KNSBN photorefractive fiber were studied. It is found that the fanning is weak when the incident angle is about 8°, which differs from that in a bulk crystal. Two wave coupling gain increases as the angle between pump beam and signal beam increases when the angle is less than 11°. It decreases as the angle increases when the angle is greater than 11°. The time evolution of transmitting signal beam at different angles was also given. The two wave coupling gain is 77 in the conditions that the angle is 8° and the signal to pump beam intensity ratio is 1∶1000, which is about 4 times that in a bulk crystal in the same conditions. The theoretical fitting and the experimental data are coincident quite well.
