Brief

The interaction of a fiber Bragg grating and longitudinal acoustic waves in a highly birefringent suspended-core fiber is investigated for the realization of a multi-wavelength reflection property.

Summary

The article explores the interaction of a fiber Bragg grating (FBG) with longitudinal acoustic waves in a highly birefringent suspended-core fiber (HB-SCF) to achieve multi-wavelength reflection. The modulated grating couples power from the fast and slow polarization modes to shifted, superposed modes supported by the grating. By adjusting the voltage of an electrical signal, the grating reflectivity of the superposed modes is tuned. The experiment successfully generated up to five different wavelength reflection peaks, demonstrating the potential for compact and fast fiber-integrated multi-wavelength dynamic filters.
