  • Abstract
    A technique for the non-destructive characterisation of couplers is proposed. A CO2 laser beam is scanned along the coupler length inducing a local perturbation to the coupler eigenmodes. Asymmetric and symmetric perturbations can give accurate mapping of power-evolution and coupler-waist shape.
