Powiązania:: https://bibliotekanauki.pl/articles/308368.pdf
Data publikacji:: 2001
Wydawca:: Instytut Łączności - Państwowy Instytut Badawczy
Tematy:: electro-optical modulator
nonlinear effects
microwave-optical mixing
Opis:: The principle of operation and the general parameters of the electro-optical Mach-Zehnder modulators are reminded in the paper. With the use of the mathematical relationships describing the transmission of the optical signal through the modulator, the theoretical model of the optical signal transmission with two modulating signals at two frequencies will be presented. The theoretical relationships describing the efficiency of the optical-microwave mixing and frequency multiplying in the two-tone operation will be derived. The analysis and the simulations will be performed for different operating points, where the nonlinearity of the transmission characteristic is specially strong.

Opis:: The most important optical devices which can be used for controlling microwave circuits will be presented in the paper. The performance and the parameters of the devices such as semiconductor microwave optoelectronic switches, photodiodes and phototransistors were described. The influence of the optical illumination on their microwave parameters will be described in details, including the our own investigations and simulations results. Several applications of such devices and their potential possibilities will be presented.

Tematy:: optical-microwave link
subcarrier multiplexing
Opis:: We describe short-distance three-channel optical-microwave link with subcarrier multiplexing for transmission digital and/or analog data between different points of industrial measurement systems. The optical fiber link operates with Fabry-Perot laser at 1300 nm, multimode, fiber and PIN photodiode receiver. From microwave point of view three carriers with frequencies 600 MHz, 800 MHz and 1000 MHz were chosen. The structure and main parameters of a link are reported and discussed.
