CST Global’s sales of lasers into the rapidly expanding PON and GPON markets exceed 25 million.

01 August 2017

CST Global, a wholly-owned subsidiary of Sivers IMA Holding AB and the UK’s leading, independent, III-V opto-electronic, semiconductor foundry has confirmed that its Indium Phosphide (InP) laser sales have exceeded 25 million and its sales of DFB lasers into Chinese and Indian GPON (Gigabit Passive Optical Network) markets are approaching 2 million.

Neil Martin, CEO at CST Global, stated, “Achieving 25m InP lasers sold into PON markets, announced in the CST Global share issue earlier this year, and almost 2m DFB lasers sold into Chinese and Indian GPON markets, is a significant milestone for CST Global. It shows that PON and GPON markets are growing world-wide and that GPON sales into developing markets offer massive potential. Most importantly, it shows that CST Global has been smart. We identified the potential and, in the last year alone, have invested in the staff, machinery and processes necessary to meet this growth.

“CST Global is now qualified to process 4” wafers. We invested in a new MOCVD capability and an Automatic Bar Stacker machine for 4” wafers, increasing our volume capability by 50%. The Automatic Bar Stacker also increases yield, by reducing human error and making the process auditable, repeatable and totally consistent. We also introduced a new Automatic Visual Inspection machine, trebling laser throughput and increasing test accuracy. This took capacity from 10,000 lasers per shift to a massive 30,000 per shift.

“The appointment of Gary Palmer, VP Operations, has seen improvements to foundry services, from epitaxial growth and fabrication, through to assembly and packaging. The appointment of Euan Livingston, VP Sales and Marketing, has allowed us to identify and engage with the right customers, in key markets around the world, alongside a consistent promotion and communications strategy.

“We also now operate in an ISO 9001:2015 quality environment. Not only has this helped streamline production, but the accreditation itself allows us to supply market-leading companies in the data centre, cloud and telecommunications markets, who expect this level of quality control.”
