Paper Abstract

We introduce a new method to make gradient index (GRIN) lenses in diffusive photopolymers with nearly arbitrary two-dimensional (2D) profiles. By modulating the 2D intensity pattern and power of the exposure with a deformable mirror device (DMD), the index profile of the GRIN lens can be controlled. Combined with the self-developing nature of the photophotopolymer, rapid on-demand printing of arbitrary micro-optics is enabled. We demonstrate the process by fabricating quadratic GRIN lenses, Zernike polynomials and multi-focal lenses.
