Micro-optics: a micro-tutorial

Micro-optics represents a rich discipline with many features not found in classical optics. Yet micro-optics is not merely 'small optics'. Using the technologies of microfabrication, entirely new fabrication processes, new materials and new types of optical devices have been conceived. Here, we provide a brief introduction to the field, discussing a variety of miniaturized optical components, as well as the materials from which they are made and the novel technologies used to fabricate them. Designed as a tutorial, this brief precis includes adequate literature references to guide the interested reader to more in-depth treatments.
