Paper Abstract

A fiber acousto-optic device is analyzed experimentally, which based on a single mode fiber coupler. The cutoff wavelength and splitting ratio in 630 nm are about 600 nm and 3 dB. When a strain wave acts on the packaged fiber coupler, the splitting ratio of the coupler will be changed which cause the modulation of output in the fiber coupler. At some frequency of strain wave, the modulation will get at Maximum.
