An extremely simple, real-time measurement technique for characterizing high-speed, low energy optical communication signals using an ultrafast SOA-based optical switch and low bandwidth electronics is presented. The technique successfully resolves pulses with an energy of 1.5 fJ in a 160 GHz pulse stream using a 10-GHz repetition rate optical control with pulse energy of only 20 fJ.
