Paper Abstract

We propose a novel kind of switch to construct a class of optical cross-connect (OXC) having both point-to-point and to-multipoint capabilities. The switch is call splitter-and-delivery (SAD) one, which has inherent multicasting capability. It is composed of splitters, 2x1 digital switches and optical gates, and is better implemented in a single silicon board using planar silica waveguide technology. Less than -40 dB crosstalk is achievable by cooperative actions of the digital switches and optical gates. On the basis of the SAD switch, we further propose three OXC architectures having different modular structures. But fundamentally, they are all strictly nonblocking and have multicasting capability. The expanding methods when the number of the fibers and the wavelengths increase a few or by a few times are comparatively demonstrated.
