Abstract:
The authors have developed a gradient method for the design of dielectric binary gratings. The method is based on using an exact differential method to solve the primal problem. Analytical matrix representations are obtained for the residual function gradient. The article provides the examples of the design of gratings for the generation of 5-11 orders with equal intensity and single-order gratings that concentrate radiation in the + 1st or –1st order. The paper considers the possibility of using singleorder gratings to design more complex focusing DOEs. It provides an example of design of highperformance binary lenses based on replacing lens zones with single-order gratings.
