The experimental comparison between two concave holographic gratings with identical recording geometries and different exposure conditions demonstrates some possibilities for the optimization of the integral diffraction efficiency.

An explanation is given for the effect of total absorption of light in grazing incidence by a sinusoidal grating, recently reported by us. The behavior of the zeros of both the first and the zeroth diffraction orders is studied numerically in the com

A detailed numerical investigation of anomalies in lossy metallic lamellar gratings is presented in a large interval of a wavelength-to-period λ/d ratio. A substantial increase in absorption (a decrease in the total diffracted energy) is observed. I

Coarse phase transmission gratings with symmetrical groove shape have found widespread use as 3-way beam splitters. Usually the light source is a laser and incidence is normal to the back surface of the grating. Theoretical energy distribution, espec

A detailed numerical study of the sinusoidal and triangular groove shape grating efficiency behavior has been carried out in grazing incidence using rigorous electromagnetic theory. The optimized parameters for maximum efficiency have been found for

Total absorption of light by highly modulated metallic gratings is demonstrated both theoretically and experimentally. This phenomenon occurs when only the zeroth-order propagates and is linked with the excitation of surface plasmons.

The diffraction efficiency behavior of reflection gratings with an asymmetrical trapezoidal groove profile has been studied. Theoretical calculations predict that at certain grating parameters superior efficiency compared to the conventional ruled gr

A heretofore unknown total absorption phenomenon on a diffraction grating has been demonstrated both theoretically and experimentally. It occurs only in a series of six special conditions, namely, groove shape, angle of incidence, groove frequency, d
