MEMS Optical Attenuators for DWDM

DWDM Technology for High Speed Optical Communications

The ever-increasing demand for applications in internet, digital cable TV, e-mail, data transmission etc. has forced the utilization of the available more than two THz transmission bandwidth of single-mode optical fiber at low loss and low dispersion window of 1550 nm. Most of the optical communication systems in use today range from 2.5 Gbit/s, 10 Gbit/s and 40 Gbit/s while 160 Gbit/s and 480 ...

MEMS for Optical Functionality

We discuss key features of MEMS technology which enable new functionalities of microphotonic devices, that can by summarized as “arrayability”, i.e. the ability to make massively parallel optical devices in a small form factor, “reconfigurability,” the ability to change optical properties spatially and temporaly, and “nano positioning,” the ability to position micro-scale devices with nanometer...

Optical MEMS for telecoms

MEMS are finding an increasing number of applications in sensors, devices, and actuators1,2. MEMS are being applied to a wide range of systems. Progress is dramatic, especially in optical telecommunications3. These applications may be divided roughly into two classes: i) those requiring precise features for optical alignment, and ii) those involving the small moving optical parts necessary for ...

Digital MEMS for Optical Switching

Over the last few years an amazing amount of interest has emerged for applications of micro electro-mechanical systems (MEMS) in telecommunications. Silicon-based optical MEMS have proven to be the technology of choice for lowcost scalable photonic applications because they allow mass manufacturing of highly accurate miniaturized parts, and use materials with excellent mechanical and electrical...
