Abstract

A dual-wavelength narrowband all-fiber acousto-optic tunable bandpass filter (DNAOTBF) was proposed and fabricated via the different vector modes coupling based on the same scalar mode induced by the flexural acoustic wave in dispersion compensation fiber (DCF). In the experiment, the resonant dual-wavelength and coupling efficiency could be electrically tuned simultaneously with a range from 1526nm of 1565nm and the lowest 3-dB bandwidth was 0.92nm.
