Paper Abstract

Planar and spatial lightwave (LW) switches (synonym: all- optical switches) are reviewed and compared with regard to their (1) architectural principles (2) possible implementations and (3) performance. The first step towards spatial LW switches are spatial LW coupler which are aimed to utilize symmetries and circular geometries covering several planar LW couplers. Then spatial LW switches, capable to generate simultaneously several rearrangeable nonblocking interconnections, are the next more involved step. The goal are switch architectures with a low number of subsequent switching sections/stages. The spatial LW switches may be applied as (1) single components and (2) switches within large 3D LW circuits. For integrated switch architectures principle problems arise and the restriction of the number of layers causes additional difficulties.
