Nonlinear diffraction fiber elements for sensor systems

The research and the development in the field of fiber optic diffractive structures with non-linear change of period and their use in realization of new optical measurement system for measurement of fast changes with frequency up to tens of kHz is the main objective of the project. The design of this system can be divided into three partial goals/parts. The design of diffractive structures with non-linear change of period as nonlinear fiber Bragg gratings (NFBG) and the design of the phase mask structures and their production technology are the first goal. The second goal is the design of an optical fiber source with active fiber and NFBG, which will be the optical source in the system. Then the third goal is the design of detection techniques and the development of the system electronics.
