GENERATION OF RADIO FREQUENCY MODULATED OPTICAL RADIATION
摘要
The invention relates to the generation of radio frequency modulated optical radiation, in particular for use in a radio over fibre communications system. It has been found that a semiconductor electroabsorption modulator can efficiently modulate 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 can be utilised to generate higher order harmonics of an electrical drive signal for use in a radio over fibre communications system.
