Abstract :
Results on S-bend losses in fibre-compatible K+-Na+ ion-exchanged waveguides are presented. For the first time a distinction has been made between pure bend loss and transition loss. Experimental results are compared to those of two theoretical models. Lateral offsets in waveguide junctions to reduce transition loss are investigated. This set of results can be used to optimise the design of S-bends with respect to length and loss.
