Integrated devices and systems for free-space optical coupling

Abstract:

Optical delivery devices and integrated analytical systems comprising the optical delivery devices are provided. The optical delivery devices include optical inputs, optical outputs, and integrated optical waveguides that are configured for coupling of optical energy to a target waveguide device through free space. The integrated analytical systems include the optical delivery devices in combination with the target waveguide device. The devices and systems 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 provide for the efficient coupling of optical excitation energy from an optical source to the optical reactions. Optical signals emitted from the reactions can thus be measured with high sensitivity and discrimination. The devices and systems are well suited for miniaturization and high throughput.
