Micromechanical Structures for Photonic Crystal Waveguide Switches

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...

All-optical switches, unidirectional flow, and logic gates with discrete solitons in waveguide arrays.

We propose a mechanism by which a number of useful all-optical operations, such as switches, diodes, and logic gates, can be performed with a single device. An effective potential well is obtained by modulating the coupling between the waveguides through their separations. Depending on the power of a control soliton injected through the potential well, an incoming soliton will either completely...

Robust Lyapunov-based Control of MEMS Optical Switches

In this paper, a robust PID control scheme is proposed for Micro-Electro-Mechanical-Systems (MEMS) optical switches. The proposed approach is designed in a way which solves two challenging and important problems. The first one is successful reference tracking and the second is mitigating the system nonlinearities. The overall system composed of nonlinear MEMS dynamics and the PID controller is ...
