Higher-order self-diffraction in bacteriorhodopsin (bR) film has been investigated. The diffraction efficiencies of higher-order self-diffraction as a function of incident intensity and order are analysed theoretically. The increase in diffraction efficiency at higher orders is due to the nonlinear transmission property of bR film, which leads to a non-sinusoidal grating shape and induces an increase in harmonic components. Calculated results for diffraction efficiencies taking into account the contribution of harmonic components are in agreement with measured results.
