A reduction of the spatial hole‐burning (SHB) effect may be achieved by a change of the structural parameters in DFB LDs. Lasers presenting phase‐shift discontinuities along the corrugation (PS DFB) or changes in the grating height (DCC DFB), or both, are seen to be more attractive in the high‐power regime than conventional DFB laser diodes. © 2000 John Wiley & Sons, Inc.
