Abstract
Analytic solutions, in terms of parabolic cylinder functions, are presented for the mode amplitudes and power in a directional coupler having a constant coupling coefficient and propagation constants that vary linearly. The solutions lead to a remarkably simple expression for the coupling efficiency.
