Abstract:
Following an analysis of the interference fringes above the plane of a high-efficiency grating, a set of systematic numerical optimizations of slanted trapezoidal gratings aiming at minimizing the maximum electric field inside the grating material was conducted. The results confirm predictions based on the interference fringe analysis. The most important conclusion is that slanting the grating ridges can substantially increase the laser-induced damage threshold of multilayer dielectric gratings.

01:17Gauss's Law in Dielectrics
Consider a polar dielectric placed in an external field. In such a dielectric, opposite charges on adjacent dipoles neutralize each other, such that the net charge within the dielectric is zero. When a polar dielectric is inserted in between the capacitor plates, an electric field is generated due to the presence of net charges near the edge of the dielectric and the metal plates interface. Since the external electrical field merely aligns the dipoles, the dielectric as a whole is neutral. An...
01:30The Electrical Double Layer
In the region where two bulk phases meet, an intricate electric charge distribution arises due to charge transfer, ion adsorption, molecular orientation, and charge distortion. This complex distribution is commonly referred to as the electrical double layer.When a solid electrode interfaces with ions in an electrolyte solution, the speed of electron transfer dictates the rates of oxidation and reduction. The electrode acquires a charge through the escape of atoms into the solution as cations or...
