Horizontal Directional Coupler Formed With Waveguides of Different Heights for Mode-Division Multiplexing
We propose a horizontal directional coupler formed with two parallel waveguides of different heights. By breaking the symmetry in both the horizontal and the vertical direction, this directional coupler can be designed to allow us coupling between any two spatial modes of a few-mode waveguide, regar...
