High-speed optical transmission experiment using PLZT optical modulator

Caption

Between the two probes you can find the PLZT optical modulator developed by the research team. The modulator is 2.5 mm in length. The waveform demonstrates the results from the two tests conducted on the optical modulator: on-off-keying method (top) and four-level pulse-amplitude-modulation method (bottom). The four-level pulse-amplitude-modulation method can double the transmission rate by using pulse signals.
