Abstract
A duplex wideband grating includes a first diffraction element and a second diffraction element. The first diffraction element and the second diffraction element may reside in a single volume or in two separate volumes. The first diffraction element may include a first set of Bragg planes, and the second diffraction element may include a second set of Bragg planes. The first diffraction element may be designed to have a peak diffraction efficiency at a first wavelength, and the second diffraction element may be designed to have a peak diffraction efficiency at a second wavelength different from the first wavelength. The first diffraction element and the second diffraction element may be designed to achieve a same angle of dispersion between wavelengths. The duplex wideband grating may have a broader bandwidth with higher average diffraction efficiency across the broader bandwidth than either the first diffraction element or the second diffraction element.
