Optical networks, with concentration, composed of directional couplers are studied. We propose a modification of N-stage planar networks. The appropriate procedure to obtain concentration in such networks is given and savings in directional couplers and switching stages are discussed.

Inspec keywords: optical couplers; optical communication equipment
