Abstract :
Mode selection in lasers is used in order to provide high-purity easy-to-implement single-mode launching in optical fibres. Mode-to-mode switching automatically maintains centring, scaling and alignment. Application of the principle to selective launching into a weakly multimode fibre (V=4) is demonstrated.
