| Summary: | In this paper, we experimentally demonstrate a
single-band self-coherent polarization-multiplexed optical orthogonal
frequency-division multiplex system with a raw data rate
of 120 Gbit/s. The transmitter uses a novel RF structure that
eliminates the need for RF mixers and optical filters. The receiver
uses a novel architecture where the optical carrier is filtered and
amplified for self-coherent detection. The receiver is polarization
diverse and allows for the usual frequency guard band between the
carrier and the sideband to be reduced in width, thus increasing
spectral efficiency. Using two commercial 20 GS/s arbitrary-waveform
generators to generate a single information-carrying band
per polarization, we achieve a raw data rate of 120 Gbit/s over 500
km of standard single-mode fiber. |
