Abstract

We discuss various practical points in the design, fabrication and characterization of form birefringent retardation plates in GaAs. The role of the substrate in the device performance is presented, together with the importance of using anti-reflection coatings. Also, we discuss the specific case of metallic reflection gratings in GaAs substrates and the resulting enhanced retardation. Finally we present the results of thermal tuning of a nominally half-wave subwavelength retardation plate.
