Design and fabrication of multilayer GRIN lenses by multi-material additive manufacturing for light coupling applications in planar optoelectronic systems

Hybrid aerosol jet μ-stereolithography additive manufacturing for fabrication of multi-material polymer step-index optics

“…10,11 However, this approach is investigated for fabrication of mechanical rather than optical components. In contrast, we have recently presented a purely aerosol-jet-based process for fabricating STIN lenses, 12 which features a discretized version of a GRIN lens. However, the sole use of aerosol jet printing technique results in low controllability of the layer thickness.…”
