We demonstrate for the first time reconfigurability of optical signals within advanced laminated composite. The approach employs an ultra-thin planar circuit, embedded glass fibre reinforced polymer (GFRP) that switches input though Ohmic heating. This advance highlights new opportunities composites, enabling data transmission redundancy and a consideration branching architectures.

The principle of Angular Multiplexing to realise independent communication channels in a relatively short step-index plastic optical fibre is described. This concept of Mode Group Diversity Multiplexing is based on the principle that the axial angle of light propagating in a step index multimode fibre is preserved over relative short distances. By using an array of lasers each launching light i...
