1. An array of integrated analytical devices, each device comprising:
- a nanoscale emission volume;
a detector layer optically coupled to the nanoscale emission volume, wherein the detector layer comprises two sensing regions, each sensing region having an edge adjacent to an edge of another sensing region or a corner adjacent to a corner of another sensing region; and
a diffractive beam shaping element disposed between the nanoscale emission volume and the detector layer;
wherein the nanoscale emission volume is positioned above the adjacent edges or the adjacent corners of the two sensing regions;
wherein light is emitted from the nanoscale emission volume by a plurality of emitters within the emission volume; and
wherein the diffractive beam shaping element spatially separates the light emitted from the nanoscale emission volume and directs the spatially-separated light to the two sensing regions.

Abstract
Arrays of integrated analytical devices and their methods for production are provided. The arrays are useful in the analysis of highly multiplexed optical reactions in large numbers at high densities, including biochemical reactions, such as nucleic acid sequencing reactions. The devices allow the highly sensitive discrimination of optical signals using features such as spectra, amplitude, and time resolution, or combinations thereof. The devices include an integrated diffractive beam shaping element that provides for the spatial separation of light emitted from the optical reactions.
