Three-dimensional nanofabrication of complex structures out of multiple materials remains a challenge. Better approaches can enable new materials, microfluidic biosensors, and photonic devices. Here I present an optical positioning and linking (OPAL) approach for assembling 3D structures out of large numbers of multi-material microscale and nanoscale building blocks. This optical tweezers-based approach provides a route for fabricating structures that were previously infeasible, including precision augmentation of microscale optical devices. Novel computational approaches that we have developed for designing new photonic devices based on the assembly of discrete building blocks will also be discussed.
