  • Method for dispersing light using multilayered structures
    Patent number: 6591035
    Abstract: A novel method and device for separating light of differing wavelengths (wavelength demultiplexing) uses a very simple and compact multilayer dielectric structure having high angular dispersion at certain wavelengths and angles of incidence. The structure is composed of alternating layers of dielectric materials of different refractive indices, and is designed to operate just outside the main reflection region rather than within the main reflection region. In this region just outside the main reflection region there is strong group velocity dispersion, causing different wavelengths of light to travel at different angles through the dielectric stack. As a consequence, different wavelength components of a polychromatic beam are separated as they pass through the device.
