Abstract

We have designed a high-efficiency array generator composed of subwavelength grooves etched in a GaAs substrate for operation at 4.5 μm . The method used combines rigorous coupled wave analysis with an optimization algorithm. The optimized beam splitter has both a high efficiency ( 96 % ) and a good intensity uniformity ( 0.2 % ). The fabrication error tolerances are numerically calculated, and it is shown that this subwavelength array generator could be fabricated with current electron beam writers and inductively coupled plasma etching. Finally, we studied the effect of a simple and realistic antireflection coating on the performance of the beam splitter.
