A flow cytometry system having a channel defined through the thickness of a substrate is disclosed. The fluid flowing through the flow path is irradiated by a first plurality of surface waveguides disposed around the flow path of the first plane while the second plurality of surface waveguides disposed around the flow path of the second plane interacts with the fluid, . The irradiation pattern provided to the fluid is controlled by controlling the phase of the light of the surface waveguide of the first plurality. As a result, the fluid is uniformly irradiated with light with a low coefficient of variation, which can improve the ability to clearly quantify fluid properties such as cell count, DNA content, and the like. |
