Abstract

The design of a diffractive phase element (DPE) that simultaneously implements wavelength demultiplexing and focusing is carried out on thebasis of the general theory of amplitude-phase retrieval. The designed DPE is fabricated with optical contact lithography. Three masks are needed to produce the surface-relief structure of the DPE with eight quantized levels in depths. Experiments demonstrate that the designed DPE can successfully implement both the functions of demultiplexing three different-wavelength beams and focusing each component at a predesignated position simultaneously. Experimental measurements are in good agreement with the results of numerical simulations. (C) 1996 Optical Society of America
