摘要:

It is shown that under practical assumptions both ray and wave theories of the prism waveguide coupler can be applied to the whole range of the coupling strength parameter 0⩽h⩽1, and yield identical results. A numerical example is given, which shows the range of validity of the weak coupling approximation.
