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 کاملIntegration of Optoelectronics and MEMS by Free-Space Micro-optics
This report represents the completion of a three-year Laboratory-Directed Research and Development (LDRD) program to investigate combining microelectromechanical systems (MEMS) with optoelectronic components as a means of realizing compact optomechanical subsystems. Some examples of possible applications are laser beam scanning, switching and routing and active focusing, spectral filtering or s...
متن کاملTranspulmonary thermodilution: advantages and limits
BACKGROUND For complex patients in the intensive care unit or in the operating room, many questions regarding their haemodynamic management cannot be answered with simple clinical examination. In particular, arterial pressure allows only a rough estimation of cardiac output. Transpulmonary thermodilution is a technique that provides a full haemodynamic assessment through cardiac output and othe...
متن کاملFree Space Optics System: Performance and Link Availability
Free Space Optics (FSO) is a telecommunications technology that transmits data in the form of optical signals across the air and, as such, can be considered as a wireless (line-of-sight) transmission system; this technology is capable of handling data rates at the Gbps level, does not require licensing, and can be deployed at one-fifth of the cost of fiber; also, the narrow beams employed in th...
