Description

This lecture covers the fabrication of gradient index (GRIN) optics using 2-photon polymerization and direct ink writing techniques. It explores the tunability of refractive index in 3D printing, porous media applications, and multi-material approaches. The presentation delves into the monomer and polymer aspects, as well as the fabrication of GRIN microoptics. Additionally, it discusses the laser energy dose effects, energy thresholds, and fabrication parameters for achieving desired refractive index profiles. The lecture also highlights the integration of microfluidic systems for multimaterial 3D printing. Various examples of GRIN glass optics, including spherical, cylindrical, and aspheric lenses, are presented, showcasing the potential for reducing optical system size and weight.
