Abstract
System and methods for analyzing single molecules and performing nucleic acid sequencing. An integrated device includes multiple pixels with sample wells configured to receive a sample, which when excited, emits radiation. The integrated device includes at least one waveguide configured to propagate excitation energy to the sample wells from a region of the integrated device configured to couple with an excitation energy source. A pixel may also include at least one element for directing the emission energy towards a sensor within the pixel. The system also includes an instrument that interfaces with the integrated device. The instrument may include an excitation energy source for providing excitation energy to the integrated device by coupling to an excitation energy coupling region of the integrated device. One of multiple markers distinguishable by temporal parameters of the emission energy may label the sample and configuration of the sensor within a pixel may allow for detection of a temporal parameter associated with the marker labeling the sample.
