First Claim
1. An integrated device for analyzing a plurality of samples in parallel, the device comprising:
- a plurality of pixels arranged on a substrate, wherein an individual pixel of the plurality of pixels comprises;
a sample well having an excitation region configured to retain a biological sample;
a first structure located adjacent to or within the sample well and configured to affect coupling of at least excitation energy into the excitation region; and
a sensing system including a sensor that is configured to discriminate between at least two different emissions from the sample well, wherein the at least two different emissions comprise spectral and/or temporal differences;
at least one excitation source on the substrate that is arranged to provide the excitation energy to the sample well; and
circuitry arranged on the substrate to receive at least one signal from the sensor.

Abstract
An active-source-pixel, integrated device capable of performing biomolecule detection and/or analysis, such as single-molecule nucleic acid sequencing, is described. An active pixel of the integrated device includes a sample well into which a sample to be analyzed may diffuse, an excitation source for providing excitation energy to the sample well, and a sensor configured to detect emission from the sample. The sensor may comprise two or more segments that produce a set of signals that are analyzed to differentiate between and identify tags that are attached to, or associated with, the sample. Tag differentiation may be spectral and/or temporal based. Identification of the tags may be used to detect, analyze, and/or sequence the biomolecule.
