Abstract:

Subject of the investigation. Electro-optical modulator circuit development capable of performing highly efficient amplitude modulation of broadband light radiation. Goal of the work. Development of a method for increasing the information density of a modulated signal based on the use of thermally stable amplitude modulation of broad-spectrum radiation in parallel channels based on sequences of Fabry–Perot electro-optical resonators. Method. The methodology of the work consists in mathematical modeling of the operation of the electro-optical modulator scheme using modulation in parallel channels of light corresponding to different non-overlapping sections of the spectrum and their subsequent summation. Main results. The principle of constructing new elements of highly efficient electro-optical modulators with parallel modulation channels based on Fabry–Perot resonators is proposed, which allows to obtain a wide-spectrum light signal consisting of a set of narrow-spectrum signals from individual modulation channels. Practical significance. The obtained results can be used to develop methods of highly efficient electro-optical modulation of the gigahertz range radiation, which is especially important for the information transmission and analysis in optical systems of location, communication and information processing.
