摘要： 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.

摘要： An optical assembly may include a platform disposed within a housing that has a limited space. The platform may be tilted by a first angle to fit a fiber array into the limited space of the housing. The optical assembly may also include a silicon photonics device mounted on the tilted platform. The silicon photonics device may include a grating coupler. The optical assembly may also include the fiber array directly coupled to the grating coupler on the silicon photonics device at a coupling position that deviates from a vertical coupling position by a second angle.
