Professor position in analogue-to-digital converters (ADC) using chipscale Optical Frequency Combs

Your mission :

The Laboratory of Photonics and Quantum Measurements ( led by Professor Tobias J. Kippenberg at the Swiss Federal Institute of Technology Lausanne (Ecole Polytechnique Fédérale de Lausanne, EPFL) in Switzerland is currently recruiting for postdoctoral candidates in the field of optical microresonators based frequency combs using analogue-to-digital converters (ADC) interfaces.

Our laboratory has developed and invented a new method to create chipscale optical frequency-combs using optical micro cavities. Frequency combs are of widespread interest for atomic clocks, spectroscopy, sensing, high capacity telecommunications as well as the calibration of astrophysical spectrometers. We have developed a new way to generate frequency combs using parametric interactions in high Q resonators on photonic chips. Such soliton Kerr frequency combs offer revolutionary advances, such as unprecedented repetition rate, fully monolithic integration and broad bandwidth. Such photonic chipscale combs have already been employed in spectroscopy, coherent telecommunications and frequency metrology.

Main duties and responsibilities include :

The postdoctoral candidate would be engaged within the framework of an EU funded project focused on the demonstration of chipscale optical frequency combs for photonically assisted spectral parallelization of ADC interfaces. Special emphasis will be on technological concepts for chip-scale integration, exploiting the complementary strengths of different photonic integration platforms to provide compact high-performance system implementations. The project brings together a strong consortium of European academic and industrial partners which are international leaders in their respective fields.

We offer :

EPFL is one of the two Swiss Federal Institutes and is known for its high international reputation and unique geographical location. It has access to large-scale 1500 square meter cleanroom facilities for nano-fabrication

The EPFL campus in Lausanne is only at a few steps from Lake Geneva and the Swiss Alps. The position is for a full time postdoctoral scholar with a full time salary and employer social. We explicitly encourage female researchers to apply.
