Photoelastic in-fibre birefringence modulator operating at the fundamental transverse acoustic resonance
IEEE Photonics Technology Letters, 5, (10), . (doi:10.1109/68.248426).
A Highly efficient photoelastic in-fiber birefringence modulator is demonstrated. It operates at the acoustic frequency ~23MHz which corresponds to the fundamental transverse acoustic resonance of a 125µm diameter silica fiber. Using an analyzer at the output end of the fiber we obtained ~90% amplitude modulation for an RF power of 0.7 W.
