Abstract :
Summary form only given. We present a simple technique for measurement of power distributions along phase-shifted DFB lasers. This is used to locate the position of the built in phase shift and to determine the grating strength, as well as to determine the older of the operating longitudinal modes. We have also demonstrated, for the first time to our knowledge, directional fiber laser output by use of a true asymmetric phase-shifted DFB structure.
