The results of studying the characteristics of integrated optical modulators of both types, amplitude and phase, developed and created at the A. F. Ioffe PTI jointly with ITMO University for quantum communication systems are presented in the article. For the first time in national practice, original technologies for the formation of optical waveguides by the method of thermal diffusion of titanium ions on crystalline substrates of X- and Z‑cuts of lithium niobate and the formation of microwave traveling wave electrodes based on galvanic silver with subsequent gilding were used to manufacture prototypes of modulators. The assessment of the main operational characteristics of the modulators is carried out. The influence of the housing design and the quality of assembly of modulators on their main parameters is revealed.
