Single-sideband (SSB) direct-detection optical orthogonal frequency division multiplexing (OFDM) transmission is experimentally demonstrated in a system with 125 km fiber length, which does not need a guard band between the carrier and the OFDM band. The waveforms of compatible SSB modulation are analytically derived and realized through a single(More)
We demonstrate an optical orthogonal frequency division multiplex (OOFDM) transmitter using a simple dual-electrode Mach- Zehnder modulator (MZM) to perform tandem single-sideband optical modulation. This allows a doubling of transmission capacity. A commercial optical transmitter card, equipped with an on-board arbitrary waveform generator, is used for the(More)
We propose the multifrequency upconversion of optical millimeter-wave (mm-wave) signal generation by an I/Q modulator. With a 90 deg phase shift, two mm-waves at different frequencies can be easily separated without interference. The receiver power penalty is less than 1 dB for the downlink 40 and 60 GHz mm-wave signals after transmission(More)
