Laboratory of 3D Printing technologies for functional Microstructures

The Project proposes the development of new generation additive laser technologies in relation to the creation of photonic devices, in particular, using direct (3+1)D letters based on femtosecond two-photon photopolymerization. The main idea of this approach is the possibility of influencing the optical and mechanical properties of the material of 3D structures both in the process of lithography and controlling the properties of the obtained optical elements by controlling external conditions such as temperature, electric and magnetic fields. Thus, in addition to the three spatial coordinates, another key independent variable for optical elements is added - the refractive index of matter.

The project is aimed at developing additive technology for creating photonic integrated circuits (FIS) and solving the most important problem of quantum photonics based on this technology - the generation of single photons with a high degree of indistinguishability. Photonic integrated circuits contain many optically interconnected components made on the same substrate and jointly performing various functions of processing optical signals (in the visible or near infrared wavelength ranges).
