Silicon Austria Labs (SAL) is Austria’s top research center for electronic based systems (EBS), which are the technological backbone of digitization. At three locations (Graz, Villach, Linz), SAL is conducting research in the areas of Microsystems, Sensor Systems, Power Electronics, Intelligent Wireless Systems and Embedded Systems to develop future-oriented solutions for industrial production, health, energy, mobility, and safety. SAL brings together key players from industry, science and research and thus valuable expertise and know-how and conducts cooperative, application-oriented research along the value chain. Cooperative projects are co-financed by SAL and enable a fast and unbureaucratic project start.

Key contributions

SAL is the coordinator of the project CoRaLi-DAR, four units from SAL will be strongly involved in the project.
The Integrated Photonics Technologies unit will be leading the work on the LiDAR photonic integrated circuit design and testing. It will focus on demonstrating that silicon photonics technology could be a viable and advantageous platform for detection and ranging application.
The Front-End Integrated Circuit unit will be working, together with FH Kärnten, in the development of dedicated electronic IC for the control of the Optical Phased Array (OPA) and signal detection. Key objective will be ensuring 50% power reduction respect to current state of the art.
The Millimeter Wave Technologies unit will strongly cooperate with Infineon in the development of new functionalities to be integrated into the RADAR system. Their effort will ensure a 50% reduction in sensor area with the introduction of a Tx/Rx duplexer.
The Heterogeneous Integration Technologies unit will lead the activities towards the final assembly of CoRaLi-DAR sensor. It will perform the necessary simulation to ensure thermal and electromagnetic compatibility between the RADAR and LiDAR sensor.

IHP conducts cutting-edge research and development into silicon-based systems, high-frequency circuits, and technologies for wireless and broadband communication. As a transition between basic and application-oriented research, the institute makes significant contributions to the innovative strength and ability of Germany and Europe as a location.

Key contributions

IHP will perform electro-photonic integrated circuit (EPIC) fabrication divided into two independent runs. The first run will test basic electronic photonic functionalities such as phase shifters and photodetectors with TIA. The second run then includes the final LiDAR chip with the integrated laser and the complete subsequent electronics and photonics. The EPIC designs in the project will be carried out by means of IHP’s PDK (Process Design Kit) and requirements of the fabrication process to be developed.
IHP will also develop the integration of laser diode sources in the proprietary EPIC platform SG25H5 in the backend. This will make it possible to have light sources integrated with a full set of photonic and electronic-based set of functionalities already developed on the platform.

CUAS (Carinthia University of Applied Science) is a university of applied sciences with regional roots and an international orientation. It is active in the priority fields of health and social affairs, business and various technology topics of engineering and constructions. Its core tasks are in the areas of study and teaching, applied research, knowledge transfer and training courses. More than 165 researchers with around 250 cooperation partners and a research volume of 8M € in 2022 bring new insights and impulses from science for business, industry, politics and society. Four research centers and 19 research groups conduct research with the aim of addressing socially and industrially relevant topics. The deliberate interweaving of teaching and research gives students the opportunity to become scientifically involved in projects up to the doctorate level at an early stage.

Key contributions

The research group of Carinthia Institute of Microelectronics (CIME) at CUAS has profound experience in the design and implementation of integrated circuits for wireless/wireline communication as well as sensor frontend integrated circuits. This includes analog and digital integrated circuit design using state-of-the-art CMOS and Bipolar technologies, system-level modeling of integrated electronic systems as well as Lab evaluation of IC prototype test chips. In the CoRaLi-DAR project, the CUAS team will be responsible for the circuit design of LIDAR receiver frontend trans-impedance amplifiers as well as the integrated Laser control circuit for FMCW LIDAR application. The research work is performed in close collaboration with partners SAL and IHP.
