Machine learning and deep learning techniques can help to guide the design process of the next generation of nanophotonics devices.  At the TU Delft, we have developed the world’s most sensitive micro-mirror force sensors using highly-strained membrane materials. Now we want to further advance this research by creating the next generation of opto-mechanical sensors via an exploratory data-driven design process. This postdoctoral position has a computational focus, but interest in learning new nanofabrication techniques is a plus. 

At TU Delft we can manipulate and engineer the highly sensitive sensors with ultra-thin materials to realize unprecedented vibration isolation which allow us to measure atto-Newton forces. Since previous design methods were based on intuition, we want to create improved designs of mechanical sensors at the nanoscale where we aim to dramatically improve the performance of these sensors via a cooperative process between computer simulations guided by machine learning and state-of-the-art nanofabrication. This will allow us to create sensors we can test in our labs, which perform far beyond the capabilities of man-made designs. This represents a unique opportunity to create a new line of sensor research by coupling the latest in artificial intelligence design with the ability to nanofabricate very complex designs on a microchip.

As a postdoc you will be working on (1) simulation of the nanophotonics device by finite element analyses; (2) new machine learning methods applicable to the problem of interest; and (3) experimental validation of the new sensor. The goal is to invert the design process from trial-and-error to computationally data-driven.

Applicants must have the following qualifications:

• strong computational skills and simulation experience (proficiency in Finite Element Analysis is a strong requirement)
• a background in engineering or physics
• coding background and willingness to learn about deep/machine learning (past experience is a plus)
• an interest in quantum technologies and applications in nanophotonics industry
• the ability to work well in a collaborative setting
• experience with optics or experiments is a plus
• good understanding of the following articles of the two PIs is a plus:
  - R. A. Norte, M. Forsch. A. Wallucks, I. Marinković, S. Gröblacher, Physical Review Letters, 121, 030405 (2018)
  - M.A. Bessa, & S. Pellegrino, International Journal of Solids and Structures, 139, 174-188 (2018).

Fixed-term contract: 1 year with possible extension to 2.5 years upon satisfactory performance.
