In this paper, a high performance integrated optical fiber acousto-optic modulator (FAMO) with operating wavelength of 1 550 nm, optical pulse rise time of 16.7 ns, optical pulse delay jitter of 1.5 ns, electric power consumption of 0.72 W(pulse operation mode) and overall size of 59.56 mm×49.48 mm×14.60 mm is designed and fabricated by using the integrated, low-power consumption and thermal simulation design technology of optical fiber acousto-optic modulator(FAOM). The modulator has the advantages of small size and low power consumption. It has a certain role in promoting the development of miniaturized low-power fiber lasers, laser wind radar and fiber-optic distributed sensing systems.
