Abstract:
We demonstrate measurement of 4x20-Gb/s all-optical OFDM signals by using loop-assisted coherent matched detector. All-optical OFDM signal is projected onto the time-frequency domain first; then, all sub-channels are restored through digital matrix processing, without relying on optical FFT.
