Abstract : A new grating phase mask is designed that allows the cancellation of the zeroth transmitted order in a diffraction configuration where the grating period is smaller than twice the exposure wavelength. An analytical treatment based on the true-mode method delivers the structure parameters, achieving 100% interference contrast. This modal approach is used to describe the modal operation of the giant reflection to zero-order device.
