Method of providing electrical separation in integrated devices and related device

An integrated device includes two sections, such as a DFB laser and an EAM modulator, having a semi-insulating separation region therebetween. The separation region is of a material acting as a trap on electrons and configured to impede current flow between the two sections due to holes. The separat...

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