LioniX International key contacts

The LioniX International team is made up of around 60 engineers, project leads and professionals. The team members you are most likely to meet during events and presentations are:

Robert Grootjans

Robert Grootjans – Head of Sales & Marketing

LinkedIn

Robert Grootjans, born in Oldenzaal, the Netherlands, studied Electrical Engineering with a specialization in microwave engineering at the University of Twente. In 2016, he began his career as a Microwave Photonics Engineer at LioniX International, focusing on high-speed signal interfaces to active components like InP. Over the years, Robert expanded his expertise across the entire spectrum of Silicon Nitride (SiN) waveguide technology, including its applications and processing. Robert is eager to explore innovative ideas and encourages anyone with challenging projects in integrated photonics to reach out to him.

Arne Leinse

Arne Leinse, PhD – CEO

LinkedIn

Arne Leinse has been active in integrated optics for more than 20 years. He received a PhD degree from the University of Twente in the integrated Optical Microsystems group in 2005. Hereafter he joined LioniX BV where he was involved in the invention and development of the TriPleX® platform from the beginning. He has been involved from the original concept until the exploitation and (co)authored over 100 articles in the last years. He has been active as Vice-President of LioniX BV in the last years and since the establishment of LioniX-international in 2016 active in the role of Chief Commercial Officer. Since January 2020 Arne is active in the role of CEO, leading the Management Team.

Portrait of Ronald Dekker, CTO of LioniX International

Ronald Dekker, PhD – CTO

Ronald brings over 25 years of expertise in material engineering, microfabrication, integrated optics, packaging, and assembly. Since joining LioniX International in 2016, Ronald has been an invaluable force in guiding the Module and Assembly group. Prior to joining LioniX International, he held various leadership positions, including senior researcher at the Integrated Optical Micro Systems Research Chair of the University of Twente and CTO at XiO Photonics, focusing on standardization and assembly methods for integrated optics. Ronald’s extensive background is grounded in his academic journey, earning a B.Sc. degree in Applied Physics and a Ph.D. degree in Integrated Optics from the University of Twente, The Netherlands.
