The PSNIU team, with the support of the NTI Competence Center Photonics, will develop the first software in Russia for the design and simulation of photonic integrated circuits (FIS). The software, called Difra lab, will speed up the development process of the FIS, as well as provide access to integrated photonics technologies for developers of telecommunications and medical systems, devices for monitoring engineering facilities and the environment.

There are no analogues of Difra lab software in Russia. Companies that develop and create photonic integrated circuits use foreign software. The emergence of Russian software will increase the independence of domestic producers and strengthen the country's technological sovereignty.

“Photonic integrated circuits are used in devices around us in our everyday life. These are high-speed Internet, tomographs, environmental monitoring systems and engineering facilities, the list goes on. It is important that reducing the time and simplifying the FIS development process will make these technologies and new types of equipment based on them more accessible to every resident of Russia,”says Boris Likhachev, Difra lab project manager.

The developers have created a prototype of the program, which is already capable of designing virtual models of photonic integrated circuits. Now the software works like this: the user determines the optical material on which the FIS will be created, step by step calculates the parameters of individual elements, then "assembles" from these elements a fully functional optical system on a chip.

This FIS development process can take anywhere from one week to six months, rather than two years. In the future, the user will be given the opportunity to build a system on a chip from already created data libraries, and the development time for the FIS will be reduced to 1-3 days.

The result of the Difra lab software is a set of topological drawings, which are then used by the manufacturer of the FIS chip in the process of its manufacture. This allows manufacturing plants to automate the manufacturing process of their products. For example, users will not have to carry out calculation cycles, comparing the obtained result with the target, and the software will allow the selection of geometry, topology, according to the user's target parameters.

“Difra lab supports work with all currently used optical materials and elements. This allows a large number of companies with different production technologies to manufacture optical chips. Simulation of individual optical elements of the FIS and the entire scheme will allow not only to predict its characteristics, but also to determine the ways of their improvement.

For this, machine learning technologies are built into the software. Due to this, the user gets the opportunity to develop a new device that surpasses analogs operating on the basis of other physical principles,”continued Boris Likhachev. The project of Perm scientists became the winner of the Start-1 competition of the Fund for Assistance to Innovation (Archipelago-2121). The final version of the software will appear before the end of 2022.
