Abstract :
Novel vertical directional couplers, consisting of graded-index planar waveguides, were realised by field-assisted K+-ion exchange in glass. Normal mode measurements of the coupling length are compared to results based on numerical simulations of the diffusion equation and the beam propagation method.
