What is it?

Applications

A multi-4-inch GSMBE 49 production system was ordered in 2022 for optoelectronic and microwave applications, particularly for growth of 1.3µm quantum dot lasers for datacom and telecom devices. The same report says such applications require very high-precision control of the epitaxial growth process.[2]
