CST Global Adds InP epitaxial overgrowth to DFB laser production

CST Global has added an in-house InP epitaxial overgrowth capability to its foundry production services. The process is critical to the manufacture of high-volume, DFB lasers used in worldwide Passive Optical Network (PON) markets.

The company says the successful implementation of this process is the result of a focused investment over the last year of approximately £500, 000 (SEK6 million).

Indium Phosphide (InP) epitaxy is deposited using a Vapour-Phase Epitaxy (VPE) process, applied by CST Global’s commercial Metal Organic Chemical Vapour Deposition (MOCVD) reactor.

“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,” commented Euan Livingston, VP Sales and Marketing at CST Global. “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.”

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

CST Global is a wholly-owned subsidiary of Sivers IMA Holdings AB.
