"Ultra-short pulse shaping using long-period fiber gratings"@en . . "The project will deal with exploitation of long-period fiber gratings for sub-picosecond pulse shaping. Fiber structures containing generally more than one grating with desired amplitude and phase characteristics will be designed and realized. One of targets will be pulse shaping generating a square or a triangle waveform from an input Gaussian pulse. These structures will be realized at the Institute of Radio Engineering and Electronics for the 1.55 \u00B5m spectral window and will be tested in the laboratory of Prof. Azana in INRS \u00C9nergie, Mat\u00E9riaux et T\u00E9l\u00E9communications, Montreal, Canada, with whom we collaborate also in the field of the design. The collaboration will be eventually broadened to structures operating in 800 nm spectral window. For these wavelengths, the testing of the structures will be realized in collaboration with Prof. Maly and Dr. Nemec at the Faculty of Mathematic and Physics, Charles University, Prague."@en . .
