The progress in microoptics and the fabrication of special-shaped aperture microlens array are reviewed. Microoptics is produced on the fabrication of gradient-index lens. The rapid progress of microoptics is urged by the application of microlens array. A new domain of microoptics is founded by the fabrication of special-shaped aperture microlens array. The theoretical and experimental researches on special-shaped gradient-index lens and special-shaped aperture microlens array are mainly discussed and useful results are presented.
