Abstract

In this paper, we present the design of a 4x4 complete interconnection network, including a new switching element configuration which allows to reduce the overall dimensions. It is based on the asymmetric passive 3-branch power divider, which allows the beam to be splitted with half power in the central waveguide and 1/4 power in either lateral waveguide. This structure, which can be inserted in various switching network architectures, has been analyzed by using the Beam Propagation Method, in order to determine as the various design parameters affect the system performances. The total area of the switching element is about 0.6 mm2 , for the control voltage of 9.7 V. The total insertion losses are 2.1 dB in the cross state and 1.2 dB in the bar state.
