 <p>Because of this difference in propagation constants, the modes travel at different speeds down the waveguide and so the field intensity oscillates between the two waveguides. This is called beating. One beat is equivalent to the coupling length, or cross-over length, and it is the length it takes for all of the power from one waveguide to be coupled into the other. As the gap between the waveguides gets smaller, the beating gets faster since <span class="math notranslate nohighlight">\(\Delta n\)</span> gets larger, making the cross-over length shorter.</p>

 <p>Now we can play around a little bit. First, we can change various lengths. We find the parameters in the <a class="reference external" href="https://gdsfactory.github.io/ubc/components_plot.html#ubcpdk.components.mzi">docs</a>. There is an ASCII drawing there that is helpful to understand what the different length parameters do.</p>

 <p>Finally, we can easily add a grating array to any component. Note that the component we want to add gratings to will be rotated so that its ports are oriented vertically. Also, though we can’t see it in the plot, adding the grating couplers also adds a label to one of the gratings, marking it as the input.</p>
