Silicon nitride (SiN) photonics is getting more and more attention due to its transparency window from visible to SWIR (short-wavelength infrared), high-power handling and most importantly its extremely low propagation loss. It is the ideal platform for photonic integrated circuit (PIC) applications such as lidar, gas sensing, bio-spectroscopy and communication. And for uses in the quantum domain such as quantum key distribution (QKD), quantum computing and quantum sensing. Yet the development of SiN photonic ICs is still far from a routine workflow. In this talk we will explore how to overcome the hurdles on the road to dedicated photonic chip design, manufacturing and prototyping.
Dr. Amin Abbasi received his BS and MSc in Applied Physics (Lasers) from the University of Tabriz, Iran, in 2009. In 2016, he finished his PhD degrees in ultra-high-speed directly modulated DFB lasers at Ghent University (UGent). He continued his research at imec/UGent on 100 Gb/s single-channel EAM modulators until 2017. Afterwards, he joined AntwerpSpace/OHB as Photonic Team Leader on microwave photonics for satellite communication. There, he contributed to various development projects for the space segment, such as OBF for SAR radar and Q-band frequency converter and receiver development for free-space communication. He joined imec in September 2020 as business development manager, covering imec’s SiN/Si 200- and 300-mm photonic platforms for sensing applications. He currently focuses on photonics integrated circuits (in Si/SiN) for optical switching and optical beamforming for lidar applications. He has (co-)authored more than 50 peer-reviewed publications.
