Abstract
The invention includes an apparatus for modulating an optical signal. The apparatus includes a spatial dispersion mechanism and a modulating mechanism. The spatial dispersion mechanism spatially disperses the optical signal. The spatially dispersed optical signal has a plurality of frequency components where each frequency component has an associated beam size. The modulating mechanism includes an array of modulating components where each modulating component has a pitch. The pitch of each modulating component is substantially equal to or less than the beam size of each frequency component.
