ENSEMBLE is a new Centre of Excellence for nanophotonics, advanced materials, and novel crystal growth-based technologies located in Warsaw, Poland, created jointly by the Łukasiewicz Institute of Microelectronics and Photonics, the University of Warsaw (Poland), the Karlsruhe Institute of Technology (Germany), the Sapienza University of Rome (Italy), and the Nanoscience Research Center nanoGUNE (Spain). The ENSEMBLE3 Centre will work on the development of novel material technologies and advanced materials with unique electromagnetic properties, with potential applications in fields such as photonics, optoelectronics, telecommunication, solar energy conversion, medicine, and aerospace.


Two PhD student positions are open in the “Optical Nanocharacterization” group, led by Dr. Johann Toudert. The group will unveil outstanding and useful optical properties at the nanoscale in innovative materials such as those developed at the Centre. It will contribute at demonstrating novel design concepts opening the path to materials and devices with unprecedented performance. A special attention will be paid to: (i) plasmonic, polaritonic, epsilon-near-zero, high refractive index, cavity, and hybrid optical phenomena; (ii) managing the harvesting and emission of light; (iii) controlling and harnessing the propagation, confinement, polarization, and spectrum of light. These properties will be explored across the ultraviolet, visible, and infrared ranges in advanced materials such as eutectic metamaterials or glasses doped with nanostructures. The exploration will be undertaken by state-of-the- art optical spectroscopy approaches (such as s-SNOM, nano- and micro- FTIR, TERS, TEF, time-resolved confocal fluorescence microscopy, micro-spectrometry). Advanced numerical analysis methods (such as transfer matrix, FEM, FDTD, effective medium, fitting, inverse problem, optimization) will be harnessed to understand the nanoscale physical origin of the measured optical properties and propose new ideas.
