A novel free-space multistage interconnection network has been proposed. The network can be implemented using a 1×2 binary phase grating (BPG) which is placed in a 4f imaging system. All optical channels from BPG have been used to form a Comega network. The optomechanical package of the Comega network was made.

Key words : optical interconnection, interconnection network, photonic switching, binary phase grating
