    Abstract: Aspects of the technology described herein relate to improved semiconductor-based image sensor designs. In some embodiments, an integrated circuit may comprise a photodetection region and a drain region electrically coupled to the photodetection region, and the photodetection region may be configured to induce an intrinsic electric field in a direction from the photodetection region to the drain region(s). In some embodiments, a charge storage region and the drain region may be positioned on a same side of the photodetection region. In some embodiments, at least one drain layer may be configured to receive incident photons and/or charge carriers via the photodetection region. In some embodiments, an integrated circuit may comprise a plurality of pixels and a control circuit configured to control a transfer of charge carriers in the plurality of pixels.

    Abstract: Systems and methods for optical power distribution within an integrated device, in a substantially uniform manner, to a large number of sample wells and/or other photonic elements. The integrated device and related instruments and systems may be used to analyze samples in parallel. The integrated device may include a grating coupler configured to receive light from an excitation source and optically couple with multiple waveguides configured to couple with sample wells. Vertical extents of optical modes of individual waveguides may be modulated to adjust confinement of light within the waveguides. This modulation may enable more uniform distribution of excitation light to the sample wells, improve excitation efficiency, and prevent overpower on regions of the integrated device.

    Abstract: Some aspects relate to integrated devices for obtaining timing and/or spectral information from incident light. In some embodiments, a pixel may include one or more charge storage regions configured to receive charge carriers generated responsive to incident photons from a light source, with charge carriers stored in the charge storage region(s) indicative of spectral and timing information. In some embodiments, a pixel may include regions having different depths, each configured to generate charge carriers responsive to incident photons. In some embodiments, a pixel may include multiple charge storage regions having different depths, and one or more of the charge storage regions may be configured to receive the incident photons and generate charge carriers therein. In some embodiments, a pixel may include an optical sorting element configured to direct at least some incident photons to one charge storage region and other incident photons to another charge storage region.

    Abstract: Apparatus and methods for improving optical signal collection in an integrated device are described. A microdisk can be formed in an integrated device and increase collection and/or concentration of radiation incident on the microdisk and re-radiated by the microdisk. An example integrated device that can include a microdisk may be used for analyte detection and/or analysis. Such an integrated device may include a plurality of pixels, each having a reaction chamber for receiving a sample to be analyzed, an optical microdisk, and an optical sensor configured to detect optical emission from the reaction chamber. The microdisk can comprise a dielectric material having a first index of refraction that is embedded in one or more surrounding materials having one or more different refractive index values.
