Micromachined Free-Space Integrated Optics
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-Fresne...
متن کاملMicromachined Integrated Optics for Free-Space Interconnections
A novel surface micro-machined micro-optical bench (MOB) has been demonstrated. Free-space micro-optics such as micro-Fresnel lenses, rotatable mirrors, beam-splitters and gratings are implemented on a single Si chip using IC-like microfabrication processes. Self-aligned hybrid integration with semiconductor lasers are also demonstrated for the first time. The MOB technology realizes a microopt...
متن کاملIntegrated three-dimensional optical multilayer using free-space optics.
An integrated three-dimensional optical multilayer system for optical data communications is presented. It is based on the use of free-space optical light propagation and combines two integration principles, namely, planar and stacked integration. The combination of both integration schemes aims at a maximal design flexibility for complex geometric layouts. On the other hand, packaging issues t...
متن کاملPlanar-integrated free-space optics with high efficiency
Planar-integrated free-space optical (PIFSO) systems have been in the center of the research at the ONT group for about 10 years. During that time, we could demonstrate the viability of this approach to build optical microsystems for applications in optical interconnection and sensing. An essential step towards practicality is now being taken, namely, the design and fabrication of systems with ...
متن کاملFree-Space Optics Wavelength Selection: 10 μ Versus Shorter Wavelengths
This paper is written in response to many inquiries about 10 μ Free-Space Optics (FSO) performance compared to shorter wavelengths. The increasing interest in better understanding FSO weather effects is the result of carrier requests as well as recent progress in analyzing fog effects on FSO signal propagation. Extensive studies in modeling fog and simulating FSO attenuations revealed the compl...
