The deep gratings with ultrahigh spatial frequencies have been developed for wavelength dispersion applications. The diffraction performances, including diffraction efficiencies, wavelength dispersive abilities and wavelength band, have been theoretically investigated. The high diffraction efficiencies, wide wavelength dispersive abilities and broad wavelength range proved the significant advantages of the developed gratings for our applications. For the fabrication process, a method for synthesizing the grating profiles to produce optimal optical performances for practical applications and for easily achieving high fidelity by microfabrication technologies has been proposed. The experimental results show that the fabricated gratings using the synthesis method have diffraction efficiencies higher than 95%, while the wide wavelength dispersions are reserved, and low diffraction fluctuations are also reduced.
