SUMMARY State of the arts on guided-wave optical switch arrays are reviewed. In this paper, electro-optic Ti:LiNbO 3 devices are mainly described in comparison with crosspoint switch element structures and switch array architectures. Packaging technologies and stability problems are discussed for practical system applications. Recent development on other materials such as semiconductor waveguid...
Abstract Additive manufacturing (AM) techniques represent a real challenge to manufacture novel composites with coupled multifunctional properties. This work focuses on the mechanical, electrical and thermal behaviours of 3D printed polymeric polylactic acid (PLA) filled carbon black (CB) conductive particles . The incorporation within polymer matrix allows for programmable conduction paths via...
In this paper, the thermo-electro-structural coupledfield in a cracked metal plate is studied using the finite element analysis. From the computational results, the compressive stresses reveal near the crack tip. This conclusion agrees with the past reference. Furthermore, the compressive condition can retard and stop the crack growth during the Joule heating process. Keywords—Compressive stres...
Automated Calibration of Balanced Control to Optimize Performance of Silicon Photonic Switch Fabrics
Abstract: Highly-efficient, fabric-wide calibration of balanced control for optical switch fabrics without built-in power-detectors is first realized with fully-automated implementation. This technique co-optimizes thermo-optic and electro-optic phase elements, correcting phase-error and power-imbalance simultaneously for optimized performance. OCIS codes: (130.4815) Optical switching devices; ...
Nowadays, shape memory polymers (SMPs)-based devices are required to be much smarter produce large recovery and force with lower working temperatures in order enable multi-functionality them. They could play a vital role the advancement of multi-functional soft robot manipulators, biomedical tools wearable where is key challenge must around body temperature, or sustainable smart systems low ene...
In this study, we first demonstrate that the J-integral in classical linear elasticity becomes path-dependent when the solid is subjected to combined electrical, chemical and mechanical loadings. We then construct an electro-chemo-mechanical J-integral that is path-independent under such combined multiple driving forces. Further, we show that this electro-chemo-mechanical J-integral represents ...
In this study, using the non-local elasticity theory, the buckling and vibration analysis of triple- walled ZnO piezoelectric Timoshenko beam on elastic Pasternak foundation is analytically investigated under magneto-electro-thermo-mechanical loadings. Using the Timoshenko beam free body diagram, the equilibrium equation of Timoshenko nano-beam model is obtained and solved by Navier’s method fo...
