Abstract: Microwave pulse generator using electro-optical sources is one of the most rapidly growing technology nowadays in the field of research which combines both microwave and optical technologies. It has many applications like it is used in radar systems, wireless communication, medical imaging, etc. We have reviewed the photonic microwave pulse generation using different methodologies and suggested new developments in this field and also studied about the different optical sources to generate light pulses and its benefits. Some techniques are also reviewed for the generation of ultra wide band (UWB) pulses in optical domain like using N tap microwave photonic filter, phase modulation to intensity modulation (PM-IM) conversion, using photonic microwave delay line filter, and using optical spectral shaping and dispersion induced frequency to time mapping. Generation of multiband and UWB signals of higher order using incoherent microwave photonic filters are also reviewed. Also, the generation of linearly chirped microwave pulses (LCMP) with large time-bandwidth product (TBWP) based on self-heterodyne technique, optically injected semiconductor laser and temporal interferometer are reviewed. Finally, all the methods are compared in terms of their advantages and disadvantages.
