Eulitha ramps tool deliveries for InP lasers
Eulitha AG, a Swiss provider of high-throughput optical lithography tools, has announced deliveries of multiple automated tools to foundries for the production of InP DFB lasers to be used in AI data centres.
The company has also reported an order backlog that will fully occupy its production capacity until the middle of 2028. The DUV photolithography tools are based on the proprietary DTL technology developed and commercialised by Eulitha, enabling the printing of high-resolution gratings required in DFB lasers.
Harun Solak, CEO of Eulitha AG, said: “Multiple DFB manufacturers have been using our tools for production for a number of years, but the volumes we have seen since 2025 represent explosive growth due to the expansion of data centres. Our technology is uniquely matched to address this patterning challenge with its high precision, resolution, and throughput. Our customers, for whom the alternative was to purchase tens of e-beam tools, were able to save significant costs by choosing our photolithography technology.”
Eulitha is currently doubling its production capacity at its location near Zurich, Switzerland, to meet the growing demand. The new production capability is scheduled to come online during the first quarter of 2027.
The company says the expansion will allow it to meet the growing demand for affordable, high-resolution patterning tools not only in optical communications for data centres but also in other areas such as light guidance for AR/VR/XR devices.
