Microwave carrier modulated by fast synchronous pulsed transitions using electro-optical gating modulators

Fast and synchronous microwave pulse bursts were obtained through optical domain amplitude modulated microwave carriers, sliced by pulse-gated modulator technique followed by photo detection. Microwave signals up to 40 GHz with pulse modulation under hundred picoseconds rise time were achieved with small jitter, and reasonable dynamic range. The technique employs laser, optical gating modulators, optical amplification, filtering, photo detection and microwave amplifiers.
