Abstract: This talk will present the silicon nitride (SiN) photonic technology developed at IMB-CNM, highlighting its scalability and versatility for integrated optics. The platform supports both Multi-Project Wafer (MPW) and dedicated fabrication runs, covering applications in the infrared (IR) and visible spectral ranges.
We will discuss the current state of the process design kit (PDK), which is stabilized for the infrared regime, and ongoing research efforts aimed at extending functionality into the near-infrared (NIR) and visible domains. These include the exploration of alternative silicon nitride stoichiometries to enhance integration density and performance, as well as the expansion of PDK libraries to support operation in the red, green, and blue wavelength regions.
The presentation will also cover the roadmap for technology evolution and the service model supporting academic and industrial collaborations.
J. Faneca’s field of expertise is photonic integrated circuits. He has a background in the design, simulation, fabrication, and characterization of photonic integrated circuits across different regions of the photonic spectrum (from visible to mid-infrared), with an emphasis on the use of open-access tools.
He has ten years of cleanroom experience, fabricating photonic integrated devices, as well as experience in complex photonic characterization setups for near-infrared devices and nonlinear integrated photonics.
He served as Manager of the Photonics Laboratory at University of Exeter between 2018 and 2020, and at IMB-CNM since 2022. Faneca has published more than 20 peer-reviewed scientific papers, accumulating over 500 citations, and has supervised several theses, ranging from bachelor’s to PhD levels.
J. Faneca is a member of the Optical Society of America (OSA), the International Society for Optical Engineering (SPIE), and the Institute of Electrical and Electronics Engineers (IEEE).
Currently, Dr. Faneca is the IMB-CNM representative for photonic integration in the Southern European Cluster in Photonics and Optics (SECPhO), in the European Silicon Photonics Alliance (ePIXfab), in QTEP — the Quantum Technologies Platform at CSIC — and is one of the leading representatives of the European pilot line for photonic chips (PIXEurope) in Spain.
