Abstract

We demonstrate an all-fiber nonreciprocal comb filter by using two acoustooptic frequency shifters and a two-mode fiber interferometer. The transmission spectra for two opposite optical propagation directions are both periodic functions of optical wavelength, but different in transmission peak wavelengths. Methods for controlling the spacing and position of the transmission peak wavelengths are demonstrated.
