WebProperties of Directional Couplers. The properties of an ideal directional coupler are as follows. All the terminations are matched to the ports. When the power travels from Port 1 … Web• The 2 x 2 fibre coupler Figure below shows the relation between the phase of the driven and the driving fibres. As a result of this phase relationship, the 2 x 2coupler is a directional coupler. That is, no energy can be coupled into a wave travelling backward in the negative-z direction in the driven waveguide.
