Abstract
This invention provides substrates for use in various applications, including single-molecule analytical reactions. Methods for propagating optical energy within a substrate are provided. Devices comprising waveguide substrates and dielectric omnidirectional reflectors are provided. Waveguide substrates with improved uniformity of optical energy intensity across one or more waveguides and enhanced waveguide illumination efficiency within an analytic detection region of the arrays are provided.
