The present invention relates to systems and methods for optical power distribution to a large number of sample wells within an integrated device that can analyze individual molecules and perform nucleic acid sequencing. The integrated device may include: a grating coupler configured to receive a light beam from a light source; and an optical splitter configured to distribute optical power of the grating coupler to a waveguide of the integrated device, the waveguide positioned to couple with the sample well. The output of the grating coupler may vary in one or more dimensions to account for the light intensity distribution of the light source. 本发明涉及用于向整合式装置内的大量样本井的光学功率分布的系统及方法，该整合式装置可分析单个分子且执行核酸定序。该整合式装置可包含：光栅耦合器，其被配置为从光源接收光束；及光学分离器，其被配置为将该光栅耦合器的光学功率分配到该整合式装置的波导，该波导经定位以与该样本井耦合。该光栅耦合器的输出可以在一个或多个维度上变化，以考虑光源的光强度分布。
