Fast optical circuit switches with large port count will allow flexible bandwidth allocation in datacenter networks by augmenting electrical packet switching. Reported herein is the development of a microsecond-speed optical circuit switch with 50×50 port counts implemented on silicon photonics platform using MEMS-actuated directional couplers. The switch contains a number of innovative enhance...

Over the last few years interests have emerged for application of MEMS in telecommunications. The use of MEMS for optical switching has turned to be the most attractive since this application could revolutionize fiber optic telecommunications. In this paper a robust control strategy based on sliding-mode control theory is developed for a MEMS optical switch, considering electrical, mechanical, ...

We report design and fabrication process of MEMS (Micro Electro Mechanical Systems) actuators for a new type of optical switch integrated with photonic crystal (PhC) waveguides. Thin film poly-silicon electrostatic microactuator (either a cantilever or a bridge style) is placed over a PhC waveguide to induce optical modulation by means of mechanical motion in the evanescent fields. For low volt...

In this paper, design, analysis and fabrication of a low loss capacitive RF MEMS shunt switch, which made on the coplanar waveguide transmission line and alumina substrate in the frequency band of 40-60 GHz, is presented. The CPW is designed to have 50Ω impedance matching on the alumina substrate. Then the desired switch is designed with appropriate dimensions. Afterward the important par...

We propose a novel two state and all-optical controllable switch using DIT, Kerr effect and interaction between quantum dots (QD) and quantum electrodynamics cavity (CQED). The two state and all-optical controllable switch is coupled to photonic waveguide from a rapid nonlinear environment (photonic crystal) and CQED. We consider the nano-crystal are doped to crystal photonic cavity as a 4-leve...
