title: Monomode all-fiber polarization modulator.
abstract: We describe a new all-fiber light polarization modulator. Its main feature is a low birefringent monomode fiber submitted to periodic stress which induces birefringence via the photoelastic effect. The fiber is inserted and glued at the antinode of a piece of fused silica which is mechanically driven by means of a piezoelectric transducer and oscillates on one of its eigenmodes. A full modulation depth is reached with <100 mW, and the stray birefringence is weak enough to allow sensitive and accurate polarimetric and birefringence measurements.
