(i) Doctorate (PhD) student position on Optical nonlinearities in lithium niobate photonic crystals
A PhD scholarship is available in the Nano Optics group at the Institute of Applied Physics at Friedrich-Schiller-Universität-Jena (FSU) to investigate optical nonlinearities in lithium niobate photonic crystals.
Lithium niobate, commonly used in optics and telecom due to its transparency in a wide wavelength range and due to its high nonlinearities, has only recently been proposed as a suitable material for photonic crystal based devices. The reason for this is that its high resistivity towards different etching techniques makes its nanostructuring a difficult task. At FSU, a process based on ion beam enhanced etching has been developed to allow the fabrication of large photonic crystals in free-standing lithium niobate membranes. The first linear optical characterizations of these structures have demonstrated a good agreement between measured properties and expected photonic effects, which is very promising for further investigations on nonlinear optics. The offered PhD project is focused on nonlinear optics in two dimensional lithium niobate photonic crystals. The main goal will be to develop photonic crystals to enhance nonlinear optical properties of lithium niobate and to understand physical phenomena that occur inside the structures. The PhD student will be mostly involved in the optical characterization of these structures, but its activities will also include fabrication and numerical contributions in collaboration with other research groups of the FSU.
Details of the position
The position is available from the earliest possible date.
Applicants are expected to have a diploma or master’s degree in physics, preferably with experience in photonic crystals.

(i) Doctorate (PhD) student position on Astrophotonics
The Abbe School of Photonics (www.asp.uni-jena.de) offers a three-years PhD studentship on a project related to applications of photonics to astronomy (astrophotonics [1]).
The incumbent will take part in research and development of high-tech astronomical instrumentation in the context of the Beutenberg Campus of the University of Jena (Germany - www.jena.de), a dynamical research environment with state-of-the art facilities for the fabrication of optical fibres (conventional and PCF) and for micro/nano lithography.
In particular, the topic of the PhD project is focused on applications for astronomical interferometry [2] and/or coronography for observation of exo-planets [3]. The goal is the exploration of new technological solutions and the realization of prototypes to be tested at the 90 cm reflector of the University’s Observatory (www.astro.uni-jena.de). Part of the time may be employed to take part to astronomical observations in Jena or elsewhere.
Details of the position
The position is available from the earliest possible date. The studentship is worth 1440 euro/month (gross).
Applicants are expected to have a diploma or master’s degree in physics, preferably with experience in experimental optics.
