We design and implement an optical slot switching network for bulk content transfer. To realize the slot switching network, we employ the generalized multiprotocol label switching (GMPLS) extension protocol to reserve and release slots dynamically according to the application. We use optical switches as relay points in the slot switching network, and we employ a 10 ns highspeed Pb,La Zr,Ti O3 (...

According to contact type, RF MEMS switches are generally classified into two categories: Capacitive switches and Metal-to-Metal ones. The capacitive switches are capable to tolerate a higher frequency range and more power than M-to-M switches. This paper presents a cantilever shunt capacitive RF MEMS switch with characteristics such as low trigger voltage, high capacitive ratio, short switchin...

The load-balanced switch architecture is a promising way to scale router capacity. It requires no centralized scheduler, requires no memory operating faster than the line-rate, and can be built using a fixed, optical mesh. In a recent paper we explained how to prevent packet mis-sequencing and provide 100% throughput for all traffic patterns, and described the design of a 100Tb/s router using t...

Abstract—A novel dual-pulse actuation voltage has been proposed to reduce dielectric charging in micro-electromechanical system (MEMS) switch, leading to a longer switch lifetime. Mathematical and transient circuit models have been utilized to simulate dielectric charging in the RF MEMS switch, enabling the analysis of charge built-up at the switch dielectric and substrate brought about by the ...

RF MEMS capacitive switches capable of orderof-magnitude impedance changes have demonstrated operating lifetimes exceeding 100 billion switching cycles without failure. In situ monitoring of switch characteristics demonstrates no significant degradation in performance and quantifies the charging properties of the switch silicon dioxide film. This demonstration leads credence to the mechanical r...

In this work, a study of MEMS (Micro electro mechanical system) and SUGAR simulator is presented. A MEMS power switch is implemented and the insertion loss, return loss with respect to frequency and ON and Off states of these loss with respect to frequency is studied. Ultra low ON state insertion loss, high off state isolation and high RF signal power handling characteristics are achieved .Many...

The load-balanced switch architecture is a promising way to scale router capacity. We explained in [1] how it can be used to build a 100Tb/s router with no centralized scheduler, no memory operating faster than the line-rate, no packet missequencing, a 100% throughput guarantee for all traffic patterns, and an optical switch fabric that simply spreads traffic evenly among linecards. This switch...
