Precise method for angular alignment of birefringent fibers based on an interferometric technique with a broadband source.


A new method for precisely aligning the principal axes between two birefringent fibers is presented using a Michelson interferometer and a broadband source. Angular alignment can be accomplished by measuring the interference peak value corresponding to the rotation angle between the principal axes of the birefringent fibers. Angular alignment accuracy is… (More)
