We make a generalization of the integral method in the electromagnetic theory of gratings to study diffraction by echelles covered with dielectric lossless or absorbing layers. Numerical examples are given that show that, as in the resonance domain,

Two-dimensional (crossed) diffraction gratings with sinusoidal or truncated pyramidal (trapezoidal) profiles are proposed to have diffraction efficiency almost independent of the incident polarization inside the optical communication spectral window

A low polarization dependent, high diffraction efficiency grating for wavelength demultiplexer is proposed, manufactured by standard crystallographic etching of Si surface. Light is incident and diffracted inside the wafer, which is covered with refl

It has long been observed that the efficiency behavior of concave gratings differs from that of the well-studied plane gratings. In particular, peak values are less, and anomalies are usually absent or at least greatly attenuated. A detailed study of

In the Omega laser fusion system, multiple laser beams are split from a single master oscillator. These beams are focused onto a reflective sphere which retroreflects the light back toward the beamsplitter. Any two of these beams can be operated as a
