Annotation: Modern telecommunication systems require high-speed and energy-efficient optical switches to process signals under dynamically changing loads. Existing solutions such as mechanical, electro-optical, acousto-optical, and thermo-optical switches have performance and control limitations, making them unsuitable for optical packet switching (OBS) and 5G/6G networks. Objective: To develop a fiber-optic fast non-relational switching device based on a dual-resonator Fabry-Perot interferometer (DIFF) with a comb-like structure of the output mirror, providing high switching speed and the ability to control directly through an optical signal. Methods used: The paper uses computer modeling methods (using the HFSS package) to optimize the design of a comb mirror and analyze the interference pattern in a diffraction pattern mixer. Analytical approaches have also been used to calculate device parameters, including the gradient of the refractive index and the sharpness of the interference pattern. Novelty: The proposed design of a diffraction pattern with a combed mirror structure that provides multi-port signal switching. Using a gradient mixer to compensate for distortion of the interference pattern. Implementation of nonrelational control, where control information is transmitted through the optical signal itself. Results: The developed device demonstrates the possibility of switching optical signals with a switching time of up to fractions of nanoseconds, which meets the requirements of modern high-speed networks. The simulation confirmed the effectiveness of a stepped-beveled comb structure for separating signals with different wavelengths. Practical significance: The device can be used in data centers (data centers), 5G/6G networks, as well as in radio frequency transmission (RoF) systems for controlling antenna arrays. The implementation of the technology will reduce power consumption and increase data processing speed, which is especially important for optical packet switching and dynamic routing tasks.
