Abstract
Reactive ion etching (RIE) is used to fabricate infrared refractive micro-optics in silicon. Three methods are used: binary optics technology which uses iterative steps of photolithography and RIE to create a multistep approximation to an aspheric profile; direct etching of a preshaped polymer microlens etch mask into the substrate; and analog etching of a lens profile directly into the substrate through a pinhole mask.
