15. An integrated device comprising:
a grating disposed on a substrate and arranged to couple radiation incident on the grating into a plurality of optical waveguides disposed on the substrate;
a first inlet to a first receiving region of the plurality of optical waveguides; and
a second inlet to a second receiving region of the plurality of optical waveguides, wherein the second inlet is offset a first amount with respect to the first inlet in a first direction approximately perpendicular to lines of the grating; and
a plurality of pixels formed on the substrate, each including a reaction chamber and an optical sensor, wherein at least one waveguide is configured to provide excitation radiation to a plurality of the reaction chambers;
wherein each reaction chamber is configured to receive a sample for genetic sequencing or protein sequencing, detection and/or measurement.
