Project description
The Internet and the overall development of the digital information society is supported by the optical networks as the underlying critical comunication infrastructure. To enable the digital evolution and the vital network services with stringent performance requirements, optical networks need to be resilient and secure. To this end, the network should maintain a high degree of situational awareness and self-adaptability.

This project will investigate the achievable levels of secure and automated operation of optical networks by addressing the related theoretical and practical challenges. Cognitive network management based on data analytics and machine learning techniques will be at the center of this project. Security-enhancing optical network design and autonomous incident remediation mechanisms shall be developed to guarantee attack-resilience, privacy and trust. Multi-domain and multi-layer networking aspects will be investigated towards achieving end-to-end trustworthiness. Novel solutions fundamental for achieving situational awareness and self-defense from malicious attacks will be devised and their usage in testbed settings will be demonstrated. The research will be a part of large international efforts in the frame of European projects TeraFlow (5g-ppp.eu/teraflow/) and AI-NET-PROTECT (www.celticnext.eu/project-ai-net-protect/).

The main research objectives for the PostDoc will be to synthesize novel molecular probes for fluorescence microscopy. The daily work will be performed at Chalmers University of Technology, in close collaboration with the Department of Chemistry & Molecular Biology at University of Gothenburg, conveniently located in the same building. Depending on the qualifications of the successful candidate, functional characterization/validation of the synthesized compounds using UV-vis/fluorescence spectroscopy and fluorescence microscopy may be included in the work.

The division and the research group
The secret life of molecules is the main theme of our research and teaching at the Division of Chemistry and Biochemistry. We are studying how small and large molecules can be produced, their interaction with one another in material or in living cells, and how they can capture and convert energy. The projects are chosen to fulfill the requirements of the highest scientific standard, and the know-how they create on a molecular level is generally of importance for solving many advanced problems as well as for future practical applications. The span of potential applications is extremely wide: from life sciences to materials sciences.

Andréasson research group is focusing on the synthesis and spectroscopic characterization of molecular photoswitches (photochromic molecules). Today, the main focus is on how to gain photonic control of energy transfer (FRET) reactions in these systems, which in turn will change the fluorescent properties. We use this scheme for many different applications, and the successful candidate will partake in a project aiming at boosting the performance in fluorescence microscopy by cleverly designed photochromic constructs.

Major responsibilities
Your major responsibility as postdoc is to perform your own research in a research group. More specifically, the main task will be to assist in the design and to perform the synthesis of the target compounds. Depending on your previous qualifications, you may also partake in the subsequent validation using fluorescence spectroscopy and microscopy. The position could also include supervising master’s and/or PhD students to a certain extent.

Contract terms
Full-time temporary employment. The position is limited to a maximum of two years (1+1).

PhD student position: Photonic-Crystal Surface-Emitting Lasers in III-Ns


As the successful candidate you will play an essential role in the development of a new semiconductor laser with emission in the blue to ultraviolet wavelength regime that has potential applications in water purification, metal processing etc. You will be given the opportunity to work in one of the world-leading groups on blue-UV surface-emitting lasers and combine device design and numerical simulations with device processing and characterization in close collaboration with partners at Chalmers within the project who are experts on photonic crystal design and collaborators at international universities who are experts on epitaxial growth.

Information about the researchThe Photonics Laboratory at the Department of Microtechnology and Nanoscience (MC2), with about 35 researchers, is working on optoelectronics, ultrafast optics and fiber optical communication. Research in optoelectronics, with an emphasis on semiconductor lasers, started at Chalmers in the early 1980’s. Today we have the expertise and infrastructure that covers most parts in surface-emitting laser development, i.e. design and simulation, laser fabrication, and material and device characterization. Realizing lasers in III-N-materials is associated with challenges such as achieving efficient electrical pumping due to the low electrical conductivity of those materials and realizing high quality mirrors to enable cavities with high quality factors. Over the past few years, we have developed nano structuring techniques for tailored optical feedback and a thin-film lift-off process to be able to combine III-N-materials with high-quality mirrors. These have enabled us to demonstrate the world’s first blue vertical-cavity surface-emitting lasers (VCSEL) with a high-contrast grating for polarization pinning and the shortest emission wavelength from an optically pumped VCSEL at 310 nm. With a prestigious collaborative research grant from the Knut and Alice Wallenberg Foundation, we are now expanding our team. Our goal in the project is to explore the use of our technologies to realize photonic-crystal surface-emitting lasers which allows for two-dimensional lasing oscillations to occur over a large area enabling, for example, high optical output powers.

Major responsibilities
As a PhD student in our group you will be exploring different schemes for photonic-crystal surface-emitting lasers in III-N-based materials. Your work will be mainly experimental and you will be trained in device fabrication using state-of-the-art equipment in our clean room as well as characterization of fabricated devices in our new measurement laboratory. In addition, you will have access to our in-house-developed simulation tools for laser design and modeling. The photonic crystal design will be done in collaboration with partners within the project. Your major responsibility as PhD student is to pursue your own doctoral studies, during which you are expected to develop your own ideas and communicate the results of your research verbally as well as in writing. The PhD position is a full-time temporary employment with a starting salary of about 3 000 Euro/month, limited to maximum 5 years. The position includes departmental work, mostly as a teaching assistant, corresponding to about 10% of the working hours.

Qualifications
By the starting date in Aug-Sept, you must have a Master of Science degree or equivalent in Physics or Electrical Engineering, with knowledge in semiconductor physics and optoelectronic devices. Any experience from device simulations, device fabrication in a clean room environment or device characterization will be a merit. You should be able to work independently as well as in a group. A good proficiency in English is a requirement.

Position summary
Full-time temporary employment. The position is limited to a maximum of five years.
