$Eulitha Displacement Talbot Lithography for AR Waveguides and DFB Lasers Eulitha showcases its Displacement Talbot Lithography (DTL) technology at Display Week 2026. Kelsey Wolley explains that DTL is a non-contact optical lithography approach designed for scalable, high-yield production of periodic structures at a cost-effective price point. This method is particularly suited for manufacturing augmented reality (AR) waveguides based on line space gratings, offering quality comparable to traditional projection systems but at a fraction of the cost, which is critical for consumer AR glasses. HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color. One demonstration features a silicon carbide AR waveguide developed with a partner, SEAF, using Eulithas DTL to define the surface-relief grating (SRG) waveguides. The company also displays a 12-inch wafer completely filled with AR waveguide designs from partner Dispelix. This is achieved by combining DTL with a step-and-repeat process, enabling seamless and sharp waveguide patterns on large substrates like high-refractive-index glass. These wafers are later cut, or singulated, into individual lenses for assembly into AR glasses. Eulitha offers a range of manufacturing tools to support different production volumes, from a small tabletop system to a semi-automatic mid-range tool and a fully automated high-volume manufacturing platform. The companys technology is compatible with various light engine approaches, including LCoS and microLEDs, as the lithography process is independent of the light source chosen by the AR device designer. The company is continuously evolving its DTL technology to open up new markets. A significant area of development is in the semiconductor laser space. Eulitha has developed a DTL-compatible method for creating gradual phase shifts in periodic structures. This overcomes previous limitations with abrupt pitch changes, enabling the high-throughput, high-precision manufacturing of devices like Distributed Feedback (DFB) lasers. This phase-shifting capability allows customers to use DTL for fabricating complex laser devices that require precise periodic structures with integrated phase shifts. While the lasers for AR projectors are a different application, the underlying advancement in DTL demonstrates the technologys expanding capabilities beyond its initial applications, addressing new challenges in photonics and semiconductor manufacturing.$
