Abstract:
An all-optical sampling OFDM scheme using PolMux-DQPSK format with single source is proposed and experimentally demonstrated. 5 × 200 Gb/s AOS-OFDM signal with spectral efficiency of 3.07 bit/s/Hz is successfully transmitted over an 80 km SMF link with real-time detection by optical Fourier transform filters. Furthermore, this scheme can coexist with traditional WDM channels and be a promising technique for seamless upgrade of transmission date rate.
