About the Job

We are searching for a creative, skilled, and ambitious candidate for our activities on developing new solutions for ultra-low noise microwave synthesis based on nonlinear integrated photonics and microcomb technologies.

Nonlinear integrated photonic circuits based on Lithium Tantalate (LT) thin films promise to revolutionize optical amplification, frequency comb generation, and microwave photonic applications with their unique combination of a strong Pockels nonlinearity, ultra-fast electro-optical modulation bandwidth, high power resilience, thermal stability, and low noise. Together with collaboration partners from Switzerland, it is our goal to develop novel ultra-low noise and high power hybrid integrated lasers and electro-optical frequency combs based on the thin-film lithium tantalate photonics platform. Using this platform, we aim to overcome limitations of contemporary microwave oscillators and extend the performance envelope of photonic integrated microwave generators based on a new electro-optical frequency division and phase noise cancellation scheme.

The objective of this work is to develop and build a hybrid integrated photonic system for the generation of ultra-low noise microwaves based on a photonic integrated microcomb and a new electro-optical frequency division scheme. The successful candidate requires a deep knowledge of optical microcomb and integrated photonis as well as strong grasp of RF technology and microwave oscillators. They will develop optical design and nanofabrication concepts and methodology to realize the photonic waveguides and circuits. Furthermore, integration of photonic components with high power semiconductor lasers is planned. The candidate will report to the Head of Department. The supervisor for this position is Associate Professor Johann Riemensberger.

Your immediate leader is Head of Department
