Photoelastic in-fiber birefringence modulator operating at the fundamental transverse acoustic resonance Academic Article uri icon

abstract

  • Abstract: A highly efficient photoelastic in-fiber birefringence modulator is demonstrated. It operates at the acoustic frequency approximately= 23 MHz, which corresponds to the fundamental transverse acoustic resonance of a 125-mu m-diameter silica fiber. Using an analyzer at the output end of the fiber, we obtained approximately= 90% amplitude modulation for an RF power of 0.7 W.
