Abstract
A comprehensive model for steady-state analysis of
polarization-mode competition in fiber distributed feedback (DFB) lasers
is presented. Effects of polarization-dependent grating nonuniformities,
polarization-dependent grating strength, coupling between the linear
polarization states due to twist or Faraday rotation, back reflections,
cross saturation from serially multiplexed lasers, as well as spatially
and polarization-dependent gain hole burning are covered by the model.
Regimes of single and dual polarization operation are identified for
different types of polarization imperfections in the cavity. The output
powers of the individual modes and the magnitudes of the hole-burning
mechanisms are also calculated anti discussed
