Using its commercial metal-organic chemical vapor deposition (MOCVD) reactor, III-V optoelectronic foundry Compound Semiconductor Technologies Global Ltd (CST Global, a subsidiary of Sweden’s Sivers IMA Holdings AB) of Hamilton International Technology Park, Blantyre, near Glasgow, Scotland, UK has supplemented its foundry production services by adding the capability for in-house indium phosphide (InP) epitaxial overgrowth, which is critical to manufacturing high-volume distributed feedback (DFB) lasers used in passive optical network (PON) markets worldwide.

Implementation of the process is the result of a focused investment over the last year of about £500,000 (SEK6m).

“Adding InP epitaxial overgrowth to our foundry capability brings a critical production process in-house, where previously it was out-sourced. It not only mitigates production bottlenecks, but also reduces DFB laser production times,” says VP sales & marketing Euan Livingston. “Over the past year, we have significantly increased the capacity of our factory in Blantyre, Scotland, to meet the high demand for DFB lasers used in PON markets,” he adds.

“Epitaxial overgrowth is a challenging process to master,” continues Livingston. “We recognize that the combined expertise of our development and operations teams has been essential to the successful introduction of this new process.”
