摘要
Dual-heterodyne mixing has been developed to detect high-speed optical signal waveforms and measure not only the amplitude spectrum but also the phase spectrum. In the present study, this method was applied to a simple experiment that demodulated intensity-modulated terabit signals, and it successfully demodulated an 80 ps non monotonic optical pulse train of 12.5 Gbps 8 bit phase-modulated signals as arbitrary waveforms with dual-heterodyne mixing. These results will be the foundation for phase-shift-keying technology that increases future communication capacity.
