摘要

实验研究了在1cm长啁啾光纤布拉格光栅中声诱导的陷波滤波器。陷波反射率(2.5 dB - 25db)和带宽(9nm - 3nm)由电信号调节。通过对实现声光调制的光栅和调制器尺寸的减小，为在标准光纤中实现更高效的声光器件指明了方向。

Wideband notch filter acoustically induced in a chirped fiber Bragg grating

A notch filter acoustically induced in a 1 cm long chirped fiber Bragg grating is experimentally investigated. The notch reflectivity (2.5 dB - 25 dB) and bandwidth (9 nm - 3 nm) are tuned by an electrical signal. The reduction of the grating and modulator size for achieving the acousto-optic modulation compared to previous works, points out for more efficient acousto-optic devices in standard optical fibers.
