Postdoc: Quantum Accelerometers for Inertial Navigation
Updated: 15 Aug 2019
Accelerometry is at the heart of a number of crucial technologies from inertial navigations to high-precision machinery. It is becoming ever more important that such systems operate in harsh environmental conditions and with quantum precision in order work autonomously from global positioning systems. Optomechanical devices based on movable nanophotonic structures offer one of the best routes towards such technologies.
At the TU Delft, we have developed the world’s most sensitive micro-mirror force sensors using highly-strained membrane materials. We now want to utilize these capabilities towards measuring accelerations in a new quantum limited regime in a form that can be readily utilized for a multi-billion euro industry. This postdoctoral position will require a focus on experimental development, simulations and nano-fabrication of computer-simulated designs.
At the 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 limited by fabrication, we want to create novel designs of mechanical sensors at the nanoscale where we aim to dramatically improve the performance of these sensors via hybrid a approach that combines photonic and phononic designs. This will allow us to create sensors which perform far beyond the capabilities of previous designs. This represents a unique opportunity to create a new line of sensor research by coupling the latest in meta-material 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) principles of inertial navigation using accelometers and micro-mirror sensors (3) experimental validation of the new sensor. The goal is to demonstrate and characterize acceleration sensitivities of these new devices in a prototype.
Applicants must have the following qualifications:
- strong experimental skills (preferably in optics), experience in finite element method simulations and/or nanofabrication
- a background in engineering or physics
- excitement to learn state-of-the-art nanofabrication
- an interest in quantum technologies and applications in nanophotonics industry
- the ability to work well in a collaborative setting
- good understanding of the following articles is a plus: R. A. Norte, J. P. Moura, S. Groeblacher, Phys. Rev. Lett 116, 147202 (2016) and A.G. Krause et al. Nature Photonics 6 (11) 768, (2012)
