Formulation of the problem. Devices such as radio-photonic-based spectrum analyzers are used to analyze radio frequency monitoring systems and complexes that can operate in a wide frequency band with high speed. The purpose of this article is to conduct a comparative analysis of new methods for improving the efficiency of optical devices in radio frequency monitoring systems.

Target. Based on theoretical research, it’s necessary to evaluate the feasibility of the created optical devices, their impact on radio frequency monitoring systems, and to assess the key characteristics of optical modulators based on integrated and additive technologies, such as speed, diffraction efficiency, approximate cost and others.

Results. The results of the study presented: the design of acousto-optic and electro-optic modulators in integral design based on diamond crystal structures; additive technology for creating and\ acousto-optic modulator based on a special mixture using 3D-printing technology; analysis and comparison of their main characteristics, The stages of the technological cycle are described, including design, modeling, material selection, additive manufacturing, post-processing and testing of components such as acoustic waveguides, optical elements and housing. Special attention is paid to minimizing dielectric losses and ensuring electromagnetic shielding. Selective laser sintering (SLS) and stereolithography (SLA) technologies are used.

Practical significance. The use of selected optical modulator designs will allow for the replacement of the other less efficient analogues and improve the performance of radio frequency monitoring systems and complexes, as well as reduce the cost and time required for their development.
