Abstract

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.
