Postdoc or PhD on "PhoQuant - Bonding of hybrid waveguide structures" (published August 2022)

The Institute of Applied Physics (IAP) at the Friedrich Schiller University Jena has a long-standing tradition and competence in design, fabrication and application of active and passive optical and photonic elements. It is also very well-known for its developments in the area of high power laser technology and nowadys also in quantum optics. Collaborative projects with companies ensure practical relevance and feasibility.

For the fabrication of waveguide structures for integrated photonics (e.g. telecommu-nication) LNOI substrates (LNOI – lithium niobate on insulator) are used. Amorphous SiO2 or other glasses are feasible as insulator. The waveguiding requires an interlayer free connection of the wave-guide with the isolator. A difference in the coefficients of thermal expansion result in mechanical stresses within the substrates during bonding, which may lead to the destruction of the whole assembly. The resulting mechanical stresses can be evaluated by means of FEM (finite element modelling) or analytical approaches. By appropriate choice of the substrate materials and their geometry or prestressing of the substrates, stresses can be reduced. Aim of this thesis is the creation of a simu-lation tool for the bonding process and experimental verification of the substrate design to achieve minimal mechanical stress.

The open positions for this topic are offered in the research group Microstructure technology of apl.-Prof. Uwe D. Zeitner. The call will be open until position is filled. The full announcement and further contact information is given here. [pdf, 345 kb]

Two PhD positions on "Ion beam doping of metasurfaces" and "Ion beam processing of quantum materials (published February 2022)

Prof. Carsten Ronning and Maximilian Zapf. Prof. Carsten Ronning and Maximilian Zapf. Image: Anne Günther (University of Jena)

The Institute of Solid State Physics seeks to fill two PhD/doctoral positions in the group of Prof. Ronning ( at the earliest possible date.

Metasurfaces are ultra-thin planar optical elements that are composed of arrays of subwavelengthsized nanostructures modulating the amplitude, phase, and polarization of light. They have enabled numerous applications such as beam shaping, optical modulation, and hologram generation. The incorporation of optically active impurities in metasurfaces would even extend the potpourri of applications. Thus, strategies for the doping of metasurfaces using ion beams should be investigated within this project. This is in particular interesting, as ion beam technologies are standard tools in semiconductor industry for e.g. precise doping in modern computer processors.

Ion beam technologies are standard tools in semiconductor industry for e.g. precise doping, enabling modern computer processors, which needs multiple ion irradiation steps. Quantum materials, such as phase-change materials and correlated electron oxides, are promising candidates for novel electronic and photonic devices – especially, if the properties can be tuned via ion beam irradiation. Thus, the damage formation, doping and recovery processes of such materials need to be investigated in detail, for example by means of in-situ electrical, optical, or mechanical measurements and accompanying simulations, which is the frame of this PhD position.

PhD & PostDoc positions on Single Photon Sources and Optical Quantum Technologies (published December 2021)

The Institute of Applied Physics is looking for several motivated and creative PhD students and Postdoctoral Researchers (m/f/d) as soon as possible for projects around single photon sources and optical quantum technologies.

Two-dimensional materials are currently a hot topic in science as they exhibit many unique properties. They promise to benefit diverse applications, ranging from electronics, optoelectronics, biomedicine, sensing and many more. Recently, it was discovered that defects in 2D materials can host stable quantum emitters, which emit single photons on demand. For wide-band gap materials such as hexagonal boron nitride (hBN), the defect states are well-isolated from the band edges, allowing for high quantum efficiencies and operation at room temperature. The single photon sources based on hBN have diverse applications; our research focus is on quantum communication, quantum imaging, and quantum sensing applications.

The successful candidates will work on the combination of room temperature quantum emitters with integrated optical systems that tailor the photophysical properties. The demonstrator devices will be benchmarked and tested in realistic scenarios. One of our key experiments is the verification of our single photon source in space on a satellite and performing a test of quantum gravity theories. We are embedded in a large international collaborative network that gives us access to a broad variety of quantum technologies, including quantum memories and state-of-the-art quantum computers.

The open positions for this topic are offered in the junior research group of Dr. Tobias Vogl. The call will be open until all positions are filled. The full announcement and further contact information is given here. [pdf, 175 kb] de
