At the European Conference on Integrated Optics (ECIO 2025), held in Cardiff, Wales (10–12 June 2025), our colleague Jessica César-Cuello (UC3M) presented the poster “Experimental Characterization of Monolithic Integrated Interleavers.” The contribution was showcased during Poster Session I at the Centre for Student Life (Poster A.05).
The work shows how two monolithically integrated optical pulse interleavers were designed and tested on a single photonic integrated circuit (PIC). These interleavers are compact, scalable, and ideal for high-speed optical systems.
Key results
-
Frequency multiplication from 20 GHz to 40 GHz
-
Extinction ratios above 20 dB, reaching up to 26 dB
-
Tuning range >15 GHz using integrated phase modulators
-
Compact, robust, and scalable design for integration into larger systems
Integrated interleavers are essential for future high-speed optical communications and signal processing. This demonstration highlights how monolithic PIC solutions can deliver performance, flexibility, and scalability – core goals of the POLYNICES project.
This work was supported by NextGenerationEU, the EPIC-Pack project, TERA6G and POLYNICES project.
