At the moment, additive technologies are important for various fields of science and technology, such as nanophotonics, optoelectronics, optics, etc. DLW (Direct Laser Writing) technology, which allows you to create 3D objects of arbitrary shape and design with high spatial resolution. The DLW method is based on two-photon photopolymerization, a phenomenon in which focused femtosecond laser radiation initiates the polymerization reaction of the main component of a photosensitive composition, the monomer, in a small volume of the photocomposition (i.e. voxel) due to the effect of two-photon absorption in the photoinitiator.
Single photon sources (SPE-Single Photon Emitters) are in demand in many quantum technologies. However, for these sources to be used for practical applications, reliable single-photon detectors are required. In photonic integrated circuits, sources and detectors, as well as functional elements, require photonic "wires" (PWB-Photonic Wire Bonds) created by the DLW method.
The report assumes consideration of the DLW method for various optical applications: the creation of elements of photonic integrated circuits (PIC-Photonic Integrated Circuits) [1], the creation and study of photonic "wires" [2] in combination with sources of single (Fock) photons and optical cavities [3].
The presented results were obtained with the support of RSF projects 22-19-00324 and 22-79-10153, as well as Subsidy Agreement No. 075-02-2022-1672 of the Russian Ministry of Education and Science.
