Amsterdam Oost, Nederland AMOLF Voltijd

**Two PhD positions: Metasurfaces for energy-efficient wave-based computing**:
**Work Activities**:
Metasurfaces are ultra-flat and compact nanophotonic elements that are pursued worldwide to replace conventional bulky optical elements like mirrors, lenses, and prisms. Going beyond simple optics replacements, metasurfaces can also perform data processing on optical signals, with particular relevance to image processing like edge detection, feature recognition, or operations that resolve wavelength or polarization information. We have two open positions addressing the following questions:

- Suppose optical signals are encoded in space like an image, in wavelength and polarization. How do you then design metasurfaces to perform common image processing steps, nowadays done on a PC, optimally in the optical domain? Can you use metasurfaces for all-optical feature extraction? What are the limits to stacking metasurfaces for more complicated algorithms? You will perform electromagnetic design and optimization, and demonstrate concepts in optical experiments
- Can we realize programmable, trainable and dynamically reconfigurable metasurfaces? Can you switch between metasurface functions by incorporating suitable materials? If so, what are the limits in energy and speed? Can you train such active metasurfaces to realize all-optical neural network functions? We envision using novel materials as metasurface constituents, such as phase change materials that show strong and reversible changes in their linear and nonlinear optical response.

**Qualifications**:
**Work environment**:
**Interacting photons group **In the Interacting Photons group we search for new physics emerging from photon-photon interactions and noise in optical resonators. We are fascinated by emergent phenomena and novel functionalities of optical systems. Most of our group members enjoy both experiment and theory.

All projects in the groups involve the use and development of advanced optical measurement techniques and nanofabrication, with extensive support from the group leader and AMOLF technical staff. The groups span the entire research cycle from developing advanced nanophotonic concepts, to theory and numerical design, to realization in the lab. Within the group as well as among the different groups at AMOLF, we have a strong focus on stimulating development of students in all professional aspects, as well as collaborations with other researchers at AMOLF and beyond. We value an inclusive and diverse environment. You will have access to state-of-the-art experimental systems that will uniquely enable you to reach the goals of this project.

**Working conditions**:

- The working atmosphere at the institute is largely determined by young, enthusiastic, mostly foreign employees. Communication is informal and runs through short lines of communication.
- The position is intended as full-time (40 hours / week, 12 months / year) appointment in the service of the Netherlands Foundation of Scientific Research Institutes (NWO-I) for the duration of four years
- The starting salary is 2.781 Euro’s gross per month and a range of employment benefits.
- After successful completion of the PhD research a PhD degree will be granted at a Dutch University.
- Several courses are offered, specially developed for PhD-students.
