Abstract

The new Russian system of computer-aided design and analysis of components of photonic integrated circuits of T1 Integration company (T1 IT holding) has been presented. The article analyzes the capabilities of domestic CAD, including in comparison with its foreign equivalent, which is widely used in enterprises of the Russian Federation. Special attention is paid to the applicability of the methods proposed by Russian developers.
