Optics and photonics are among these research fields impacted by MEMS techniques. These micro optical devices and systems are inherently suited for cost effective wafer scale manufacturing as the processes are . Much higher resolutions than ultrasound imaging, so early cancer detection possible. Much safer and much lower cost than CT and MRI, leading to affordable cancer screening to save millions of lives. Noninvasive or minimally invasive imaging, enabling real-time surgery monitoring to .

The reason is the unique MEMS characteristics that are advantageous in.

Fundamentals of Micromachining.

Driven by communications industry. Couplers, demultiplexers, switches, routers, etc. Mostly elements, not complete systems. Current Trends in Optical MEMS. University of California, Berkeley.

Review of Optical MEMS Devices. Micropositioners for mirrors and gratings. High-resolution raster scanner. Although very powerful, most of them have rela- tively simple functionality. Constant demand for mobility, interconnectivity and bandwidth is causing rapid expansion of the telecommunication infrastructure across the world.

We discuss key features of MEMS technology which enable new functionalities of microphotonic devices, that can by summarized as “arrayability”, i. Particularly, the combination with optical components has been very successful and have led to optical MEMS. The technology of choice for us is the silicon-on- insulator (SOI) . Abstract—The intensive investment in optical microelectro- mechanical systems ( MEMS ) in the last decade has led to many successful components that satisfy the requirements of lightwave communication networks. In this paper, we review the current state of the art of MEMS devices and subsystems for lightwave.

The scalability and cost of microelectromechanical systems ( MEMS ) optical switches are now the important factors driving the development of MEMS optical switches technology. The employ- ment of MEMS in the design and fabrication of optical switches through the use of micromachining fabricated micromirrors expands . WITH INTEGRATED ON-CHIP ELECTRONICS.
