1. An apparatus for modulating spectral phase and spectral amplitude of a received optical signal, comprising:

  • a spatial dispersion mechanism for spatially dispersing a received optical signal;

    a modulating mechanism comprising a plurality of modulating components, associated ones of the modulating components operable for adapting relative phases of respective portions of the spatially dispersed optical signal, the phase-adapted portions of the spatially dispersed optical signal being adapted for modulating spectral phase of the received optical signal; and

    a spatial filtering mechanism adapted for destructively interfering the phase-adapted portions of the spatially dispersed optical signal for modulating spectral amplitude of the received optical signal.
