Abstract :
The effect of high hydrostatic pressure on polarization properties in highly birefringent (HB) optical fibers is experimentally evaluated up to 200 MPa. The results are discussed in terms of beat-length changes under high pressure. It is found that oscillatory behavior of the output signal exiting from the HB bow-tie fiber and monitored in the plane parallel to one of its own two principal axes can be attributed to a pressure-induced increase of beat-length parameter. This effect can be applied to sense high hydrostatic pressure using appropriately configured HB fiber, but it could be a disadvantage in underwater communication systems using HB fibers if these are not adequately protected.
