Job Description:

Imaging technologies form the basis of a vast range of products and devices and improvements would have a huge impact both scientifically and commercially. We have identified a key bottleneck, how light is modulated in the imaging system, that we can unlock to achieve a new paradigm in imaging technologies. Spatial light modulators, and similar components, operate sequentially: the light beam is shaped in different patterns but the time interval between patterns is limited by the refresh rate of the device. We will remove this limitation, thereby creating a technological breakthrough; our advance will be to send all possible patterns of the device simultaneously, and encoded in a short nanosecond pulse, creating the concept of parallel beam shaping or dynamic spatio-temporal light modulation device. In Dynamo, we will shape optical beams in two spatial dimensions plus the temporal one. The equivalent refresh rate of the dynamic pixel will start at GHz, although we are confident it will become much higher by the end of the project. To give an idea of our ambition, we compare this improvement in the time to process images with the improvement in the clock frequency of computers: the first general-purpose electronic computer, the ENIAC, had a clock frequency of kHz. It was not until AMD reached 1 GHz in their computers. Processing images is broadly similar to processing data so this is indicative of the fifty-year acceleration in the realm of imaging that we will achieve. Dynamo is an ambitious and integrated project that begins by studying the fundamentals of acoustic wave scattering and ends by developing ultra-fast imaging applications in optics. The success of this pathway requires the synergy of the disciplines of physical acoustics, photonics and imaging. The outcomes from this project offer to accelerate imaging technologies and place European science and industry at the forefront of the inventions and advances that will follow.

Main tasks of the candidate

The main tasks that will be carried out within the project include:

• Fabrication and optimization of different nanostructures exhibiting photonic and phononic properties
• Design and building optical set-ups for the optical characterization of the nanostructures
• Fundamental study/characterization of materials and devices using, e.g. advanced spectroscopy.

Requirements

We look for an enthusiastic researcher familiarized with the fields of photonics/plasmonics and:

• PhD in Materials Science, Nanoscience, Physics or similar subjects.
• A good level of written and spoken English.
• Optical setups know-how and optical spectroscopy background.
• Nanofabrication experience, knowledge of vacuum and cleanroom work environments.

Details of the position

• Contract (full time) duration for 2 years, within the project funded by the European Union, HORIZON-EIC--PATHFINDEROPEN GA.
