Abstract

A structure includes a dielectric waveguide, and at least one grating coupler adjacent the dielectric waveguide. Each grating coupler includes a set of parallel optofluidic grating channels oriented orthogonally to the dielectric waveguide. The structure may also include a radiation source operatively coupled to the dielectric waveguide, and an optical receiver such as a photosensor adjacent the grating coupler(s). The structure may be used as part of an optofluidic sensor system for, for example, biochemical applications.
