Paper Abstract

2D networks of directional couplers (DCs) and Mach-Zehnder interferometers for of all optical switching in the 3D physical space are presented and arising problems and their solutions are made transparent. The result also applies to optical signal processing. The all-optical 2D switching networks, based on 4-gon switches, are compared of 2 by 2, 3 by 3 and 4 by 4 couplers and nearest-neighbor interconnections where the crucial problem is the implementation of >= 3 by 3 couplers. However, various advantages are expected (1) combination of the massive parallelism of optics and the parallelism in the frequency domain (2) considerable reduction of the number of stages (3) novel properties which are caused by the increase of freedom contributed by the additional space coordinate and (4) an increase of the range of possible applications.
