An ultra-wideband all-optical single-sideband modulation technique based on a wavelength converter using a semiconductor optical amplifier Mach-Zehnder interferometer was experimentally demonstrated. Optical single-sideband signals with a carrier frequency of 100 GHz were generated.
An all-optical frequency upconverter using an optical interleaver and a semiconductor optical amplifier (SOA) has been experimentally demonstrated for radio-over-fiber (RoF) applications. An optical radio frequency (RF) signal (fRF=25 GHz) consisting of an optical carrier and a sideband is generated by mixing an optical intermediate frequency (IF) signal (fIF=1 GHz) with an optical local oscillator...
We have experimentally demonstrated a full-duplex wavelength division-multiplexing-based radio-over-fiber system using all-optical single-sideband (SSB) frequency upconversion and wavelength re-use techniques for broadband optical-wireless access networks. The optical SSB RF signal having the RF frequency of 62.5 GHz is generated by using this all-optical frequency upconverter that consists of an...
