Title: Micro-transfer-printing of thin-film devices on silicon nitride photonic integrated circuits: on-chip lasers, modulators, and detectors

Abstract: Silicon nitride photonic integrated circuit (PIC) technology has come forth as one of the main photonic integration platforms. Silicon nitride PIC technology has many great features such as low waveguide loss, a wide transparency range (400 nm – 4000 nm), and the possibility of low-cost mass manufacturing using CMOS infrastructure. Yet, many applications require on-chip lasers, modulators, and detectors, which are not available in standard silicon nitride PIC technology. This talk will show how a technique called micro-transfer-printing can be used to integrate thin-film devices, made out of various materials, with silicon nitride PICs to realize on-chip lasers, modulators, and detectors. Micro-transfer-printing can be done in a massively parallel fashion on a wafer-scale, thereby offering a path to high-volume, low-cost production.

Speaker bio: Artur did his BSc degree in Engineering (Electronics and information technology) from the Vrije Universiteit Brussel in 2012. Afterwards, he entered the European MSc in Photonics program during which he spent a semester at Ghent University, the Vrije Universiteit Brussel, the University of St Andrews and the Swiss Federal Institute of Technology in Lausanne (EPFL). At EPFL, he did his master’s thesis with Professor T. J. Kippenberg. In 2014, he joined the Photonics Research group to work on low-temperature processed thin films of second-order nonlinear optical materials for silicon nitride photonic integrated circuits, under supervision of Professor R. Baets and Professor S. Clemmen. For this work he was awarded a PhD degree in 2019. Currently, he is working as a postdoc in the Photonics Research Group on III-V-on-SiN mode-locked lasers.

Artur’s work at MIT will focus on visible-spectrum photonics for quantum control, with a particular focus on cold atom control with our CUA collaborators Profs Vuletic, Lukin, and Greiner.
