The deep-etched LNOI waveguides (HDLN process) developed at EPFL were successfully transferred to the spin-off company Luxtelligence for future exploitation. Luxtelligence adopted the know-how from EPFL and was responsible for the nanofabrication of the photonic devices using the HDLN process throughout the project. This resulted in the realization of verified components designed by VLC Photonics […]

The HDLN PDK has been fully implemented in the GDSFactory design environment, providing a flexible, script‑based framework for photonic layout development. Through GDSFactory, users can access parameterized cells, validated component libraries, layer definitions, and automated design‑rule checks aligned with the fabrication process. This integration supports efficient circuit design, layout generation, and the reliable reuse of

After the development of basic components and more advanced building blocks, the full potential of the HDLN platform was demonstrated with applications in communications and microwave photonics. We conducted data transmission experiments using intensity modulation and direct detection, as well as coherent schemes, achieving data transmission using 16-state quadrature-amplitude modulation (16QAM) at symbol rates up to 200 GBd (see Fig. 1(a)). Furthermore, we used the Mach-Zehnder modulators (MZM) developed in HDLN to convert ultra-broadband analog electrical

Lithium Niobate has emerged as a promising platform in the field of integrated photonics. Like other mature photonics platforms, Lithium Niobate boasts low material absorption, allowing for the development of ultra-low-loss photonics waveguides. What sets Lithium Niobate apart is its electro-optic effect, which holds immense potential to revolutionize communication, sensing, and computing technologies. However, a
