Multi-photon three-dimensional microfabrication (3DM) is a photolithographic technique that enables topologically complex 3D micro-structures with feature size as small as 1 \u03bcm or less to be generated in a single exposure step by nonlinear photo-patterning in a material. The photo-patterning is initiated by coherent multi-photon excitation (MPE). The material may be a glass, a polymerizable resin, or even a heterogeneous composite, such as a resin containing dispersed nano-particles. 3DM offers great promise as a tool for generating complex micro-devices, such as MEMS, micro-fluidics, and micro-optical components. The publication below provides a comprehensive review of the 3DM technique.<\/p>

The NPM group is developing new material systems for 3DM and applying the technique to create a wide range of functional micro-structures. Of particular interest are micro-structures that\u00a0perform a photonic function<\/a>, interact with or sense biological species, or mimic a biological function. The limiting resolution, or the dimensions of the smallest feature that can be generated, is determined by the optical parameters of the excitation geometry and the physical and chemical response of the material to MPE. We are exploring new optical configurations to\u00a0improve the resolution in 3DM<\/a>. Examples of Dr. Kuebler’s work in 3DM can be found in the publications below.<\/p>
