University of Twente: Integrated Optical Systems (iOS) Our Integrated Optical Systems (iOS) group is a research group dedicated to advancing the key-enabling technologies related to integrated photonics. The group focuses on the development and optimization of novel optical materials, low-loss, and high-gain waveguide platforms, 3D photonic architectures, and advanced light coupling solutions over a broad spectrum range from UV to IR. The research carried out by the iOS group covers a range of applications, including but not limited to telecommunications, lidar, biosensing, and wafer-level optical testing. Our activities range from design and fabrication (using the excellent clean-room facilities of the MESA+ Institute for Nanotechnology) to optical characterization in the iOS laboratories. In the QU-PIC project, the iOS group at the University of Twente will be responsible for developing fast (into GHz-range) on-chip modulators that can operate down to UV wavelengths to enable the application to signal conditioning in (on-chip) ion clocks. iOS will take up a leading role within the QU-PIC project for the device design and characterization, as well as fabrication, which will happen in the MESA+ Institute for Nanotechnology. The modulators will be fabricated in an Aluminum Nitride (AlN) photonic platform, also developed within the scope of the QU-PIC project. Efforts will be made to optimize the RF reactive magnetron sputtering process, as well as the lithography, etching, and annealing steps. Once developed, the AlN devices will be integrated into the low-loss Al2O3 UV platform by Aluvia Photonics. Qu-PIC
