Abstract

An integrated device includes two sections (A, B), such as a DFB laser (A) and an EAM modulator (B), having a semi-insulating (SI) separation region therebetween. The separation region (24) is of a material acting as a trap on electrons and configured to impede current flow between the two sections (A, B) due to holes. The separation region (24) may be of a material acting as a trap both on electrons and holes. Alternatively, the separation region (24) is of a material that acts as a trap on electrons and is provided over a p-type substrate (20) common to the two sections (A, B).
