Photoelastic in-fibre birefringence modulator operating at the fundamental transverse acoustic resonance

By I. Abdulhalim and C.N. Pannell

Abstract

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
