ATR Imaging Optical Component Using Segmented Waveguides

The patent segments the polychromatic light source into multiple monochromatic light sources, each dedicated to a specific wavelength. This is achieved by using multiple planar waveguides with distinct diffraction gratings, where each waveguide receives and guides light at a specific wavelength to the sample. This segmentation allows each wavelength to be delivered with high power density simultaneously, eliminating the need for scanning and dramatically reducing acquisition time.

The patent transitions from a simple prism (2D planar structure) to a multi-dimensional optical component consisting of multiple superimposed planar waveguides with distinct diffraction gratings. Each waveguide operates in a separate dimensional space, guiding specific wavelengths independently. This dimensional expansion allows simultaneous multi-wavelength illumination of the entire sample field, eliminating scanning and reducing acquisition time while maintaining manageable device complexity through integrated fabrication.

The patent merges multiple planar waveguides with distinct diffraction gratings into a single integrated optical component. All waveguides and gratings are fabricated together on the same substrate using the same process, combining what would otherwise be separate components into one unified device. This merging approach enables simultaneous high-speed imaging at multiple wavelengths while controlling device complexity through integrated manufacturing, where the complexity is managed as a single component rather than multiple separate systems.
