Abstract
Radio frequency modulated optical radiation is generated for use in a radio over fibre communications system. A semiconductor electroabsorption modulator efficiently modulates an input optical signal at harmonics of the electrical modulation frequency applied to the electroabsorption modulator. A low frequency design, and thus low cost, electroabsorption modulator is utilized to generate higher order harmonics of an electrical drive signal for use in a radie over fibre communications systems.
