【Abstract】 The characteristics of fiber acousto optic coupled ring resonators were studied. It is found that a novel acousto optic coupled ring resonator can be got for the frequency shift and filtering characteristics of the acousto optic fiber coupler. Theory and experiments have demonstrated that such a resonator has a unique feature that it can convert continuous laser to pulse train caused by the interference of multiple beams with accumulative shift frequencies in the fiber loop.更多还原
