Abstract
We discuss the design, fabrication and optical performance of a broadband f orm-birefringent quarter-wave plate for the 3.5 to 5 mu m wavelength region . Rigorous coupled wave analysis (RCWA) was used to design the requisite su bwavelength grating for silicon substrates in ambient air. Fabricated sampl es yield a measured phase retardation of 89 degrees to 102 degrees over the desired wavelength range. (C) 1999 Optical Society of America.
