Abstract
AbstractDifferential group delay (DGD) generation by inducing birefringence in uniform fiber Bragg gratings (FBG) is studied. Applying a transverse load, a birefringence is induced on a uniform FBG creating a tunable differential group delay. A theoretical behavior of this phenomenon is presented being in good agreement with the experimental results obtained. A maximum experimental tunable DGD of ∼60 ps was obtained with this induced birefringent process in the uniform FBG. © 2007 Wiley Periodicals, Inc.
