Diffraction efficiencies for transverse electric and transverse magnetic waves transmitted by a Bragg grating with a single-layer antireflection coating, plotted here as a function of deviation from the central Bragg wavelength λB. This grating has a Bragg angle of π/6, a thickness of 500 Bragg wavelengths, and an average index of refraction of 1.4.
