About the position

The advancement of laser, optical amplifier, and advanced photonic integrated light source technology is a cornerstone for the application of optics and photonics in a manifold of research and technology fields ranging from optical fiber communications, metrology, environmental and medical sensing and imaging, and for applications in fundamental sciences such as laser spectroscopy. Establishing a new paradigm for continuous- and travelling-wave nonlinear integrated photonics with hybrid integrated pump laser sources facilitates the exploration of new applications of optical sources, in particular for quantum-enhanced metrology and spectroscopy, which so far have struggled to transition from the lab to the field. The performance envelope of the nonlinear optical system is intrinsically linked to the properties of the active nonlinear material. Therefore, much of the research in nonlinear integrated photonics focusses on the exploration of numerous different material systems ranging from III-V, diamond, silicon carbide, doped glass, etc., that overcome the limitations of traditional nonlinear platforms like lithium niobate, silicon or silicon nitride, always with the goal of unlocking a stronger nonlinearity while reducing optical propagation loss. New optical waveguide technologies that have emerged in the last decade are thin-film lithium niobate, -tantalate and III-V large bandgap semiconductors such as gallium phosphide, which unlock new capabilities for nonlinear photonics on chip with modest power optics and without the need for high-Q resonators.

The advertised project will focus on the development of nonlinear photonic integrated circuits for new lasers and optical parametric oscillators based on III-V and II-VI semiconductors. The successful candidate will develop new platforms and applications for nonlinear light generation in the mid-infrared wavelength region based on developing new classes of on-chip frequency comb sources and parametric frequency converters.

The candidate will report to the Head of Department. The supervisor for this position is Associate Professor Johann Riemensberger.
