    Optical processing – Motivation
  Conventional approach: all-electronics – “wireless-like”




Unsustainable with respect to:
                                      - Dissipation,
                                      - Scalability,
                                      - Channel Rate.

    Optical processing – what role?

 Not compatible with complex operations
 Increased optical-layer functionality
 Much faster than picosecond (GHz)
 Can be used for specialized spectral/temporal,
  fast manipulation.
 Serves as a bridge to electronic plane, not as an
  competing technology
