The authors propose and demonstrate direct electron-beam writing of surface relief diffractive elements into hybrid inorganic/ organic sol-gel glass films. The etch depth and phase delay can be controlled by the electron dose. The potential applications include multi-phase-level diffractive elements and apodised planar waveguide gratings.
