摘要：

Methods for reducing or eliminating longitudinal spatial hole burning in AR-coated, index-coupled DFB lasers are discussed. It is shown that elimination of spatial hole burning in DFB lasers can be achieved by the introduction of well-chosen variations of coupling strength and/or internal absorption in the longitudinal direction. Approximations for these structures are modeled numerically and fabrication methods for these approximate structures are suggested.
