We demonstrate micrometer scale mid-IR lenses for integrated optics, using solution-based inkjet print-
ing techniques and subsequent processing. Arsenic sulfide spherical microlenses with diameters of
10350 m and focal lengths of 10700 m have been fabricated. The baking conditions can be used
to tune the precise focal length. 2011 Optical Society of America

1. Introduction
Mid-IR (MIR) technology has emerged as a con-
stantly growing market over the past decade. While
formerly used for materials processing and medical
procedures mainly, MIR technology is now a major
part of current research in sensing and military ap-
plications, as well as wireless communication [14].
This development has been further encouraged by
