Paper Abstract

We present a brief overview of a promising switching technology: Silica-on-Silicon thermo-optic planar lightwave circuit integrated circuits (PLCs). This 2-D solid-state optical device is capable of non-blocking switching operations and several additional important built-in functionalities. Both enable single-to-single channel switching, and single-to-multiple channel multicasting/broadcasting. In addition, it has the capability of channel weighting and variable output attenuationlpower control, for instance, to equalize signal levels and compensate for unbalanced different optical input powers, or to equalize unbalanced EDFA gain curve. We mention the market segments appropriate for the switch size and technology, followed by several application examples: (1) Core networks use cross-connect systems to establish connections among nodes as well as among network segments; (2) Switching to protect and restore network service.
