Abstract
An optical modulator includes an optical pulse train generator that forms an optical pulse train of a predetermined frequency at a generator output. The optical modulator also includes an optical pulse train modifier having a first input optically coupled to the output of the pulse train generator, a second input, and an optical output. The modifier produces a modulated optical pulse train related to a signal appearing at the second input and having an optical sub-carrier frequency related to the predetermined frequency of the optical pulse train at the first input.
