Application Deadline: application is open until positions are filled
The Laser Physics and Nonlinear Optics group (LPNO) in the University of Twente, the Netherlands, is seeking candidates for two PhD projects on the topic of nonlinear integrated photonic signal processing in silicon nitride. These vacancies are part of the project LiSbon: Light and sound sound-based signal processing in silicon nitride, the NWO Vidi project of Dr. David Marpaung.
The goal of the LiSbon is to develop an advanced signal processing technology based on the exquisite light and hypersound interactions in a silicon nitride-based nanophotonic circuit. This socalled Brillouin integrated signal processor will serve as a critical technology for spectrum management and utilization in future wireless and optical networks.
The two PhD projects are complementary but are at the same time are expected to be highly collaborative. The first project will focus on developing a new CMOS compatible integrated photonic platform that supports efficient stimulated Brillouin scattering (SBS) and the creation of a functional and tunable Brillouin processing circuit. The second project will focus on the application of the Brillouin signal processor in the areas of microwave photonic signal processing and optical communications. Creation of a reconfigurable processor through hybrid integration with an optical frequency combs source will be explored.
In both projects, the PhD candidates are expected to study, design, and characterize nonlinear optical devices with enhanced opto-acoustic interactions. They will perform radio frequency and optical experiments to utilize the realized devices for advanced signal processing. Parts of the research will be performed in a close collaboration with industrial partners including LioniX International and PhoeniX Software in Enschede and Smart Photonics in Eindhoven.
We are looking for two highly motivated PhD candidates with a background in photonics, physics, applied physics, optoelectronics, electrical engineering, or closely related areas. In particular, involvement in one or more of the following topics is desired:
- Design, fabrication, or experimental characterization of integrated photonic devices and circuits
- Modeling or experiments of nonlinear optical phenomena in optical fibers or integrated waveguide devices, in particular stimulated Brillouin scattering (SBS)
- Experimental characterization of microwave photonic devices and systems or optical communication systems
- Modelling or experimental work on optical frequency combs and their applications
- Study of integrated optomechanical devices
English language proficiency is strictly required. Curiosity and strong scientific communication skills are desired. A scientific presentation will be part of the interview process.
We want you to play a key role in an ambitious project in an inspiring international environment.
- Two PhD positions for four years, full time with a probationary period of one year
- A starting salary of € 2.222,- in the first year and a salary of € 2.840,- in the fourth year gross per month;
- Excellent mentorship, a stimulating research environment, and world-class research facilities.
- Various professional and personal development programs
- A green and lively campus, with lots of sports facilities and other activities
About the group
The Laser Physics and Nonlinear Optics group (LPNO) explores the physics and technology of nonlinear optical processes and lasers with emphasis on nanophotonic approaches. This includes a wide range of light intensities and time scales, research on novel light sources, that are of importance for emerging photonic technologies, such as in telecommunications (integrated microwave photonics), precision metrology or optical sensing. The research currently includes integrated nonlinear optics, integrated quantum optics, and integrated laser physics. The group participates in strategic alliances with various partners, including the Applied Nanophotonics (ANP) Research Cluster and the MESA+ Institute for Nanotechnology.
