Abstract

We demonstrate micrometer scale mid-IR lenses for integrated optics, using solution-based inkjet printing techniques and subsequent processing. Arsenic sulfide spherical microlenses with diameters of 10-350 μm and focal lengths of 10-700 μm have been fabricated. The baking conditions can be used to tune the precise focal length.
