Abstract
A method and apparatus are provided for modulating a laser beam with an information signal. The method includes the steps of modulating a plurality of coherent, optical signals with a respective information signal of the plurality of information signals and directing the modulated optical signals onto a photodiode. The method further includes the steps of detecting the collected signals in the photodiode and refractively synchronizing the laser beam with clock reference signals which allow easy separation of the modulated signal blocks at the receiving end of the fiber optic.
