The illumination beam profile. (a) Experimentally measured 2D intensity profile of the illumination beam in the center of the channel parallel to the flow (XZ-plane). (b) The layout of collection gratings is sketched on top of a simulated distribution of the intensity distribution of the electric field component |Ey|2 (the component perpendicular to the flow and parallel to the plane of the chip) at the plane of the gratings on quartz calculated using a 3D FDTD model built for a 6 µm polystyrene bead entering the illumination beam.
