Abstract

A blazed surface relief transmission grating is commonly used to efficiently defract light into a single order, but the relationships governing the optical behavior have not been well described. The Finite Difference Time Domain (FDTD) computation technique has been applied to optics simulations in recent years [1,2,3] and is here applied to a blazed grating . The propagation details are shown clearly, and the reasons behind them are explained.
