Programmable All-Fiber Optical Pulse Shaping

A Novel Approach to Generate Chirped Waveform by using Chirped Lithium Niobate Mach-Zehnder Modulator

“…Finally we used a concept of optical pulse shaping for the generation of chirped waveform due to its advancement and easiness, by using a LiNbO 3 Mach Zehnder Modulator which acts as an optical pulse shaper. Beside optical pulse shaping technique some other techniques also include the generation of chirped microwave pulses like wavelength to time mapping and photonic microwave delay line filter [6]. In an optical spectral shaping and wavelength to time mapping for generation of chirped microwave arbitrary waveform by shaping the spectrum of an ultrashort optical pulse with a filter (usually FBG) that have a capacity to linearly increase or decrease the free spectral range (the frequency space between two consecutive transmission peak) and the spectrum shaped pulse is then linearly mapped to the time domain in dispersive element [7].…”
