1. A system comprising:
an array of reaction chambers;
first and second waveguides configured to deliver excitation light to at least a portion of the array of the reaction chambers; and
a dummy structure disposed between the first and second waveguides, wherein:
a vertical extent of an optical mode of the first waveguide is modulated to adjust confinement of light within, and along a length of, the first waveguide; and
the dummy structure extends in parallel to the first waveguide along the length of the first waveguide.
