Versatile acoustooptical flexural wave modulator, filter and frequency shifter in dual-core fibre
Versatile acoustooptical flexural wave modulator, filter and frequency shifter in dual-core fibre
We report the fabrication and experimental characterization of efficient flexural-wave acoustooptical modulators in velocity-mismatched dual-core dual-mode fibre. Coupling efficiencies of 100% and beyond, tunable from a few hundred kHz to several MHz, are obtainable over device lengths of 30 cm. A travelling flexural wave, excited by a silica horn, causes coupler rephasing when the acoustic wavelength equals the normal mode beat length. The device has negligible insertion loss, and through its tunability and reconfigurability has considerable potential in a variety of WDM, switching and signal-processing applications.

Abstract
We report the fabrication and experimental characterization of efficient flexural-wave acoustooptical modulators in velocity-mismatched dual-core dual-mode fibre. Coupling efficiencies of 100% and beyond, tunable from a few hundred kHz to several MHz, are obtainable over device lengths of 30 cm. A travelling flexural wave, excited by a silica horn, causes coupler rephasing when the acoustic wavelength equals the normal mode beat length. The device has negligible insertion loss, and through its tunability and reconfigurability has considerable potential in a variety of WDM, switching and signal-processing applications.
