Abstract
A grating dry-etched through the upper wells of a multiquantum-well ac tive layer has been characterized before and after regrowth. TEM obser vation and carrier lifetime measurements have shown growth-free defect s of the epitaxial layers, As a consequence, quasi-100% monomode oscil lation on lambda + 1 mode has been achieved on complex-coupled distrib uted-feedback lasers fabricated with such grating.
