Micromachined Free-Space Integrated Optics

چکیده
We report a novel surface-micromachined micro-optical bench (MOB) technology which enables us to monolithically integrate "flipped-up" free-space optical elements with micro-positioners and micro-actuators. This technology allows complete optical systems be implemented on a single Si chip using IC-like microfabrication processes. We have, for the first time, successfully fabricated micro-Fresnel lenses, mirrors, beam-splitters, gratings, and precision optical mounts, as well as rotational stages and other micro-positioners. Self-aligned hybrid integration with edge-emitting lasers and vertical cavity surface-emitting lasers (VCSEL) are also demonstrated for the first time. The MOB technology could significantly reduce the size, weight, and cost of most optical systems, and has a significant impact on optical switching, optical data storage, optoelectronic packaging.

متن کاملMicromachined Vertical Three-Dimensional Micro-Fresnel Lenses For Free-Space Integrated Micro-Optics
We report the first fabrication of vertical three-dimensional micro-Fresnel lenses with polysilicon materials by surface micromachining technique. Micro-Fresnel lenses play a very important role in micro-optics because of their thin film structures and their ability to achieve very short focal lengths. Although micro-Fresnel lenses have been studied and well understood [ 11, the lens planes usu...
