Addressed Photonic Differentiator Based on Fiber Bragg and Moire Gratings Structure

For photonic differentiators, which, as a rule, are considered as separate devices, the issues of their network multiplexing for a single module of photonic processing and computing of multiple signals, as well as the stability of differentiation characteristics with deviations in the temperature regimes of the laser and differentiator with a corresponding mismatch of their central wavelengths, are not touched upon. The advantages of microwave photonic processing of information used for addressed fiber Bragg structures will make it possible to solve the above problems of photonic differentiators when they are combined into a network. This conclusion is proved by the procedure presented in the report for the synthesis of combined addressed fiber Bragg structures, one of component of which is the Moire grating and the unity of their structure with the structure of photon differentiators.
