We present a novel scheme of overcoming laser diode (LD) intensity modulation bandwidth limitation by effectively improving modulation depth and simultaneously generating optical single sideband for radio-on-fiber applications. Our scheme uses wavelength-selective amplification characteristic of an LD under modulated light injection. The 17-GHz optical single sideband signals are generated with a 2.5-Gb/s-grade distributed feedback laser with wavelength-selective gain from a Fabry-Perot LD. The 155-Mb/s data transmission at 17 GHz is successfully achieved.
