This paper describes a fully integrated micro-optical system, in which dynamic angular control of the beam from a VCSEL (vertical cavity surface emitting laser) is realized by laterally moving a collimat¬ing diffractive lens in the light path. The l

Publikováno v: Frontiers in Optics 2004/Laser Science XXII/Diffractive Optics and Micro-Optics/Optical Fabrication and Testing.

A novel technique is presented for integrating diffractive optical elements onto silicon. The processing is made in a reverse order as the diffractive lens is first embossed in a plastic layer on the silicon wafer.
