A Perspective on the Reliability of MEMS-Based Components for Telecommunications
Despite the initial skepticism of OEM companies regarding reliability, MEMS-based devices are increasingly common in optical networking. This presentation will discuss the use and reliability of MEMS in a variety of network applications, from tunable lasers and filters to variable optical attenuators and dynamic channel equalizers. The failure mechanisms of these devices will be addressed in te...
متن کاملDigital 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...
متن کاملMEMS Technology -- Micromachines Enabling the “All Optical Network"
* Formerly with Lucent Technologies/Agere Systems (Breinigsville, PA) Abstract Research on micromachines or MEMS technology has been ongoing for more than a decade. Early work focused on biomedical, printing and airbag applications. Only recently has this technology been applied to telecommunications networks. This new micro-optics technology, known as Optical MEMS, is enabling a new generation...
متن کاملSecond Order Sliding Mode Observer-Based Control for Uncertain Nonlinear MEMS Optical Switch
This paper studies theuncertain nonlinear dynamics of a MEMS optical switch addressing electrical, mechanical and optical subsystems. Recently, MEMS optical switch has had significant merits in reliability, control voltage requirements and power consumption. However, an inherent weakness in designing control for such systems is unavailability of switch position information at all times due to t...
متن کاملMEMS reliability from a failure mechanisms perspective
Over the last few years, considerable effort has gone into the study of the failure mechanisms and reliability of microelectromechanical systems (MEMS). Although still very incomplete, our knowledge of the reliability issues relevant to MEMS is growing. This paper provides an overview of MEMS failure mechanisms that are commonly encountered. It focuses on the reliability issues of micro-scale d...
