Using optical technology for the design of packet switches/routers offers several advantages such as scalability, high bandwidth, power consumption, and cost. However, reconfiguring the optical fabric of these switches requires significant time under current technology (microelectromechanical system mirrors, tunable elements, bubble switches, etc.). As a result, conventional slot-by-slot schedu...

The ability of silicon micromachining to produce small, precision, movable parts provides an opportunity for MEMS component use in optical communications networks [1,2]. To address this potential market, Analog Devices has developed the Optical iMEMS process for fabricating MEMS optical components with integrated, onchip electronics. While this process could be used to make a variety of optics ...

The flange climb derailment is one of the cause of derailment for a typical switch. The derailment for the switch is a complex phenomenon since the contact area is changing dynamically. The contact angle between the wheel flange and the switch point is investegated in terms of the risk on the derailment. The contribution of this study is proving that UIC716R standard recommendation about the sw...
