Abstract :
A hybrid LPE/MOCVD growth procedure is described which enables ¿ = 1.55 ¿m distributed feedback laser structures to be fabricated without deformation of the corrugated region of the device. Depths of corrugations remaining after overgrowth using this process are typically 1600 Ã
. Conditions under which deformation does occur are also presented.
