Aixtron announced today that Lumentum has ordered multiple G10-AsP MOCVD systems for InP-based laser and detector production, driven by surging demand from AI datacenter networks. The InP epitaxy buildout is accelerating.

Every one of these new reactors ships with LayTec in-situ metrology. That part is well known. Less appreciated is that LayTec is expanding revenue beyond sensor modules with a second, very different product.

In a recent update, LayTec is quietly scaling its EpiX C2C mapping station as a second revenue pillar.

Most investors associate LayTec with sensor add-ons on MOCVD reactors, like those in every Aixtron G10-AsP ordered by Lumentum. The EpiX C2C is fundamentally different: a standalone, fully automated production tool with cassette-to-cassette wafer handling, FOUP load ports, wafer-ID reader, and cleanroom-grade fan-filter units. This is fab-floor equipment, not an accessory.

EpiX scans finished epitaxial wafers point by point and builds a full 2D map showing whether layer thickness, composition, and light emission are uniform across the wafer, essentially a quality control step before the wafer moves into the next process stage.

LayTec has also introduced pre-configured product packages for two fast-growing compound semiconductor markets:

InP Optoelectronics, optimized for NIR photoluminescence mapping of InP laser and detector structures (900–1700 nm), used in AI datacenter transceivers and CPO GaN Power Electronics,or AlGaN barrier composition and thickness mapping in GaN-on-Si wafers, relevant for EV infrastructure and datacenter power delivery.

Previously, EpiX required custom configuration per material system. Now standardized application packages with pre-programmed analytics reduce adoption friction and shorten sales cycles as demand rises.

With EpiX C2C, LayTec monetizes each fab beyond in-situ sensors. A typical workflow now spans three touchpoints: in-situ epitaxy monitoring, ex-situ wafer mapping via EpiX, and in-situ plasma etch monitoring. Revenue per fab becomes multiple times higher than a single sensor add-on.

LayTec appears to be very well positioned and strategically prepared for the accelerating demand in InP and GaN applications. If LayTec were a standalone company, this would look like a classic picks-and-shovels compounder. As part of Nynomic’s photonics portfolio, it sits in a group trading at ~1.2x sales, with LayTec likely contributing ~15% of revenue.
