Workpackage 4: Optical processing sub-system development

Work areas :

• Bit serial Circuit Design and Modelling • Hybrid Integrated Circuit Fabrication • Individual Device and Subsystem Characterisation • Control firmware & software development

Hybrid integrated optical circuits required :

• Programmable optical bit filter • Optical bit pattern matching circuit

• Optical buffer memory • Optical routing switch

• Control firmware for the operation of the hybrid integrated circuits

• Validation of individual hybrid integrated subsystems at wirespeed (40Gbit/s)

Establish a bit serial circuit design suitable for the architecture that has been chosen in WP2, model the hybrid integrated circuits.

• Establish proportion of all-optical to electronic processing which is most practical for this work.
